My Top 10 Tools for Learning 2010

For this year’s edition of the Top 100 Tools for Learning (a continuing series started, hosted and curated by Jane “Duracell Bunny” Hart of the Internet Time Alliance) I decided to really reflect on my own Learning Process. I am a knowledge worker and need to learn every single day to be effective in my job. I have agreed with my manager to only do very company-specific formal training. Things like our Leadership development programs or the courses around our project delivery framework are so deeply embedded in our company’s discourse that you miss out if you don’t allow yourself to learn the same vocabulary. All other organised training is unnecessary: I can manage myself and that is the only way in which I can make sure that what I learn is actually relevant for my job.

So what tools do I use to learn?

1. Goodreads in combination with Book Depository
The number one way for me personally to learn is by reading a book. When I started as an Innovation Manager in January I wanted to learn more about innovation as a topic and how you could manage an innovation funnel. I embarked on a mission to find relevant books. Nowadays I usually start at Goodreads, a social network for readers. I like the reviews there more than the ones on Amazon and I love the fact that I can get real recommendations from my friends. Goodreads has an excellent iPhone app making it very easy to keep a tab on your reading habits. I found a bunch of excellent books on innovation (they will get a separate post in a couple of weeks).
My favourite book store to buy these books is Book Depository (please note that this is an affiliate link). They have worldwide free shipping, are about half the price of the book stores in the Netherlands and ship out single books very rapidly.

2. Twitter and its “local” version Yammer
Ever since I got an iPhone I have been a much keener Twitter user (see here and guess when I got the iPhone). I have come to realise that it is a great knowledge management tool. In recent months I have used it to ask direct questions to my followers, I have used it to follow live news events as they unfold, I have searched to get an idea of the Zeitgeist, I have used it to have a dialogue around a book, and I have used it as a note taking tool (e.g. see my notes on the Business-IT fusion book, still available thanks to Twapperkeeper).
Yammer is an enterprise version of Twitter that is slowly taking off in my company. The most compelling thing about it is how it cuts across all organizational boundaries and connects people that can help each other.

3. Google
Google does not need any introduction. It is still my favourite search tool and still many searches start at Google. I have to admit that those searches are often very general (i.e. focused on buying something or on finding a review or a location). If I need structured information I usually default to Wikipedia or Youtube.

4. Google Reader
I have about 300 feeds in Google Reader of which about 50 are in my “first read” category, meaning I follow them religiously. This is the way I keep up with (educational) technology news. What I love about Google Reader is how Google has made a very mature API available allowing people to write their own front-end for it. This means I can access my feeds from a native iPhone app or from the web or from my desktop while keeping the read counts synchronised. Another wonderful thing is that Google indexes and keeps all the feed items once you have added the feeds. This means that you can use it to archive all the tweets with a particular hash tag (Twitter only finds hash tags from the last two weeks or so when you use their search engine). Finally, I have also used Google Reader as a feed aggregator. This Feedburner feed, for example, was created by putting three different feeds in a single Google Reader folder (more about how to do that in a later post).

5. Wikipedia (and Mediawiki)
The scale of Wikipedia is stupefying and the project still does not seem to run out of steam. The Wikimedia organization has just rolled out some enhancements to their Mediawiki software allowing for easier editing. The openness of the project allows for people to build interesting services on top of the project. I love Wikipanion on my iPhone and I have enthusiastically used Pediapress a couple of times to create books from Wikipedia articles. I find Wikipedia very often (not always!) offers a very solid first introduction to a topic and usually has good links to the original articles or official websites.

6. Firefox
Even though I have written earlier that I was a Google Chrome user, I have now switched back and let Mozilla’s Firefox be the “window” through which I access the web. This is mainly due to two reasons. The first being that I am incredibly impressed with the ambitions of Mozilla as an organization. Their strategy for making the web a better place really resonates with me. The other reason is Firefox Sync, allowing me to use my aliased bookmarks and my passwords on multiple computers. I love Sync for its functionality but also for its philosophy: you can also run your own Sync server and do not need to use Mozilla’s and all the sync data is encrypted on the server side, needing a passphrase on the client to get to it.

7. LinkedIn
It took a while before I started to see the true benefits of LinkedIn. A couple of weeks ago I had a couple of questions to ask to people who have experience with implementing SAP Enterprise Learning in large organizations. LinkedIn allowed me to search for and then contact people who have SAP Enterprise Learning in their profile in some way. The very first person that I contacted forwarded me on to a SAP Enterprise Learning discussion group on LinkedIn. I asked a few questions in that forum and had some very good public and private answers to those questions within days. In the past I would only have access to that kind of market information if SAP would have been the broker of this dialogue or if I would buy from analysts like Bersin. LinkedIn creates a lot of transparency in the market place and transparency is a good thing (especially for customers).

8. WordPress (including the WordPress.com network) and FocusWriter
Writing is probably one of the best learning processes out there and writing for other people is even better. WordPress is used to publish this post, while I use a simple cross-platform tool called FocusWriter to give me a completely uncluttered screen with just the words (no menus, window edges or status bars!). WordPress is completely free to use. You can either opt for a free (as in beer) hosted version that you can set up within seconds on http://www.wordpress.com or you can go the free (as in speech) version where you download the application, modify it to your needs and host it where you want. If I was still a teacher now, this would be the one tool that I would let all of my students use as much as possible.

9. Youtube
The quantity of videos posted on Youtube is not comprehensible. It was Rob Hubbard who first showed me how you could use the large amount of great tutorials to great effect. He rightfully thought: Why would I put a lot of effort into developing a course on how to shoot a great video if I can just link to a couple of excellent, well produced, short, free videos that explain all the most important concepts? The most obvious topics to learn about are music (listening to music and learning how to play music) and games (walkthroughs and cheat codes) , but there are already lots of great videos on other topics too.

10. Moodle and the community on Moodle.org
Moodle is slowly slipping to the bottom of my list. In the last few years a lot of my professional development was centred around Moodle and I still owe many of the things I know about educational technology, open source and programming/systems administration to my interactions in the forums at Moodle.org. Two things are the cause for Moodle being less important to my own learning:
1. I now have a job in which I am tasked to try and look ahead and see what is coming in the world of enterprise learning technology. That is a broad field to survey and I have been forced to generalise my knowledge on the topic.
2. I have become increasingly frustrated with the teacher led pedagogical model that all Virtual Learning Environments use. I do believe that VLEs “are dead”: they don’t fully leverage the potential of the net as a connection machine, instead they are usually silos that see themselves as the centre of the learning technology experience and lack capabilities to support a more distributed experience.

Previous versions of my Top 10 list can be found here for 2008 and here for 2009. A big thank you again to Jane for aggregating and freely sharing this hugely valuable resource!

Parallax Revisited 1 Year of Constraints

Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. July marks the first year of the parallax series. To celebrate we look back on the past year and review our: favourite topic, favourite personal post, favourite post of the other and a review of the formats. You can read Arjen’s post with the same title here.

When I started blogging in the summer of 2008 I decided I would stay away from writing “meta posts”. I never like it when people write about their own blog (how many posts they have made, comments received, visitors had, etc.). If you don’t like that either, then I suggest you skip this post as I am going to break my own rules.

Parallax
When Arjen Vrielink and I realised that we would no longer work together at Stoas Learning, we decided that it would be nice to stay in touch and find a way to continue the conversations we had. Arjen thought it would be a good idea to write a monthly blog post. We would share a title and we would publish at the exact same time linking to each others posts. Neither of us would read what the other had written before the posts were published. I thought “parallax” would be a good name for the series as it is the name for the fact that two viewers looking at the same thing from a different location see something different. We did as we agreed and have now written twelve parallax posts. This is number thirteen.

Formats
Each parallax post comes with restrictions. The idea being that constraints actually induce creativity. We have used different types of constraints. The most simple limitation was on the number of words. We used this a couple of times and each time it forced me to rewrite a lot. This probably created better English (which isn’t my mother tongue as you might have noticed) and more readable posts, but also forced me to leave out arguments and points that I thought were important. Other times we forced each other to use a particular medium (e.g. a video or a type of picture) , we stole a format of a magazine (e.g. the “What on earth is” series by Linux Format) or we used Tweets about an event to tell a story (e.g. Drupaljam). I have come to realise that these constraints can really be helpful in the writing process and I would like to continue to explore new formats.

My favourite post
One of the nicest things that can happen when writing a blog post is receiving comments. It is therefore that my post titled A Design Concept For a Mobile Moodle Application is one of my favourites. Writing the post allowed me to think quite deeply about what a Mobile application for Moodle should look like and it integrated some of the ideas that I had had for a long time. It triggered a lot of discussion with a fast reply from the lead developer from Moodle and it made connections to other people who are making these ideas a reality.

My favourite post written by Arjen
It has been interesting to see how often Arjen and I take a very similar approach to a topic. One example being the similar kind of caveats we have written in reaction to the title of the post. Arjen’s posts are often more blunt than mine and slightly more provocative. Many of his posts have made me laugh out loud.
My favourite post of his is the one titled What on earth is Remote Sensing?. It starts with the classic question: “I’m not interested in another Swami theory, so please …” and then goes on explaining a relatively complex topic, “remote sensing”, in an extremely clear and humorous way. I like it when writers manage to open up a new world for me and that is what Arjen did with this post.

My favourite topic
Parallax has also created the time and space to write about the things that I always meant to write about, but could never get to. The Influence of a Workspace On Performance is probably my favourite topics where this was the case. This post brought together my thoughts on how the environment affects behaviour allowing me to use great examples from people like Corbusier, Hans Monderman, Jane Jacobs and David Leon (and from products like IE6). These topic continues to fascinate me and I would gladly write another post exploring some of these ideas further.

The future of parallax
Looking back I can now clearly see the way forward for Parallax. I think it has more than delivered on what it set out to do:

It made me stay in touch with Arjen: at least every month we have some email back and forth on the topic and the constraints and sometimes we do things together so that we can write about it.
It helps me accomplish one of the main goals of my blog: reflection. I am not naturally a very reflective person and don’t take the time to think (every second of open time is spent reading or listening to informative podcasts, I never stare in the distance and ponder, sadly making my morning shower the most reflective part of the day). Writing is reflecting and thinking and would be worth it even if nobody would ever read this.
It allows me to react on my very “corporate” job. I can, covertly, challenge some of the ways of working in my company and think about doing things differently.
It opens up conversations with people from all over the world.

The one thing that I would like to do in the future is to get more guest writers to participate. I think it would be great to have a constantly changing third voice to our posts. I hope Arjen agrees!

Christopher Alexander’s “A Pattern Language”

I have just finished reading Christopher Alexander‘s A Pattern Language: Towns – Buildings – Construction, one of the most wonderful books I have read in years.

The scope of the book is incredible. It sets out, in plain terms, to empower people to design, build and shape their own surroundings. It does this by creating a “pattern language”, a kind of generative grammar with 253 patterns that can be used to make things. The patterns move from big town scale patterns (e.g. The Distribution of Towns, Magic of the City, Web of Shopping, Nine per Cent Parking), via medium building scale patterns (e.g. Wings of Light, Intimacy Gradient, Staircase as a Stage) to small construction scale patterns (e.g. Structure follows Social Spaces, Low Sill, Filtered Light, Different Chairs).

Each pattern is described in a similar way: there is a picture showing an archetypal example of the pattern, then a paragraph describing the context of the pattern (in which larger patterns does this pattern fit), next in bold a headline giving the essence of the problem, then a research based exploration of the problem, next in bold the solution stated as an instruction, then a diagram as a visual way of describing the solution and finally a paragraph describing which smaller patterns can help this pattern. Each pattern also comes with a label signifying how sure the authors are that this truly is an universal pattern.

The breadth of topics in the book is baffling (it took the authors about seven years to research and write it). Let me just give you some random quotes to show you what I mean (doing the book a gross injustice by leaving out a lot of context).

On the magic of a cities:

The magic of a great city comes from the enormous specialization of human effort there. Only a city such as New York can support a restaurant where you can eat chocolate-covered ants, or buy three-hundred-year-old books of poems, or find a Caribbean steel band playing with American Folk singers.

On the evils of supermarkets:

It is true that the large supermarkets do have a great variety of foods. But this “variety” is still centrally purchased, centrally warehoused, and still has the staleness of mass merchandise. In addition, there is no human contact left, only rows of shelves and then a harried encounter with the check-out man who takes your money.

On grave sites:

No people who turn their backs on death can be alive. The presence of the dead among the living will be a daily fact in any society which encourages its people to live.

On why buildings should have gradients of intimacy:

When there is a gradient of this kind, people can give each encounter different shades of meaning, by choosing its position on the gradient very carefully. In a building which has its rooms so interlaced that there is no clearly defined gradient of intimacy, it is not possible to choose the spot for any particular encounter so carefully; and it is therefore impossible to give the encounter this dimension of added meaning by the choice of space. This homogeneity of space, where every room has a similar degree of intimacy, rubs out all possible subtlety of social interaction in the building.

On why your windows should have relatively small panes:

[Thomas Markus] points out that small and narrow windows afford different views from different positions in the room, while the view tends to be the same through large windows or horizontal ones. We believe that the same thing, almost exactly, happens within the window frame itself. [..] The view becomes alive because the small panes make it so.

On lighting every room from two sides:

When they have a choice, people will always gravitate to those rooms which have light on two sides, and leave the rooms which are lit only from one side unused and empty.
This pattern, perhaps more than any other single pattern determines the success or failure of a room. The arrangement of daylight in a room, and the presence of windows on two sided, is fundamental. If you build a room with light on one side only, you can be almost certain that you are wasting your money.

On modern impersonal interior design:

Do not be tricked into believing that modern decor must be slick or psychedelic or “natural” or “modern art,” or “plants” or anything else that current taste-makers claim. It is most beautiful when it comes straight from your life – the things you care for, the things that tell your story.

On high buildings (imposing a four story limit):

There is abundant evidence to show that high building make people crazy.
High buildings have no genuine advantages, except in speculative gains for banks and land owners. They are not cheaper, they do not help create open space, they destroy the townscape, they destroy social life, they promote crime, they make life difficult for children, they are expensive to maintain, they wreck the open spaces near them, and they damage light and air and view. But quite apart from all this, which shows that they aren’t very sensible, empirical evidence shows that they can actually damage people’s minds and feelings.

I could go on and on…

Written in 1977 it is clear that this is a very “seventies” book. The belief in what we in The Netherlands would call “De maakbaarheid van de samenleving” (the ability to create/design/mold society) is very high. It was interesting to reflect on where I grew up and how much of that place was designed according to the same kind of thinking and ideals. I could also find many of seventies based educational philosophy of the school I used to work at in the book. The open doors, the integration of inside and outside, there are even some very explicit ideas on education and learning in the book.

Although many of the patterns are probably very universal (they are very human), I do think the book has some strong cultural biases. This doesn’t make it less valuable though.

The book has really made me want to scratch my own creator’s itch. It makes you want to design things. (Apparently Will Wright, the creator of SimCity, wanted to create this game after reading the book).

What I want to create, inspired by this book, is not a town or a house. I want to write a new pattern language. Wouldn’t it be great if we had a generative grammar for technology enhanced education (or using another term, online learning events)? I see that there have been some attempts to do this already (here and here), but I would love to create a much more extensive work that is in the style of Alexander. Is there anybody who would like to help me? Shall I start a wiki?

If you want more information about the book, then go to its website or read hyperlinked summaries of all patterns.

ReWork Rehashed

Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about the 37signals book Rework. Each of us will write about the three things in the book that we already do, about three things we will do from now on going forward and about three things that we wish our employers would do from now on. You can read Arjen’s post with the same title here.

Jason Fried and David Heinemeier Hansson of 37signals and Ruby on Rails fame have just written a new book titled: Rework (you can download a free PDF excerpt). Reading it gave me an ambivalent feeling: these authors are obviously very good in what they do and they have managed to build a successful business monetizing different parts of their talents, but the book feels like a monetization effort too and the number of words per Euro are very low. Arjen Vrielink has written a quite damning review on Goodreads.

Nonetheless it has some interesting lessons to offer. It has about 100 pieces of advice for people starting their own business or working in a business. Some of the advice I already practice, some advice I will try to practice from now on and I wish that the company I work for would practice some of the advice going forward.

Three chapters about things I already do:

Build an audience (page 170)
Traditional PR and marketing is about going out and trying to reach people. The ubiquity of the Internet allows you to let people come to you instead of the other way around.

When you build an audience, you don’t have to buy people’s attention – they give it to you. This is huge advantage.
So build an audience. Speak, write, blog, tweet, make videos – whatever. Share information that’s valuable and you’ll slowly but surely build a loyal audience. Then when you need to get the word out, the right people will already be listening.

Emulate chefs (page 176)
In this chapter the authors make a case for sharing everything you know, something which is anathema in the business world. They use famous chefs as an analogy. The best chefs share their most valuable recipes in their cookbooks. Why? Because they know that their business as a whole cannot be copied. What better way to show you are an excellent cook, then by sharing your recipes?
I am convinced that there are only benefits to sharing everything I know about educational technology and innovation with anybody who is willing to listen. Doing this is the only way to take part in the incredibly valuable discourse on this topic and taking as much out of it as possible.

Forget about formal education (page 215)
Companies still over-value formal education from. I have personally decided to attend as little formal education as possible from here on further. The key qualities that somebody needs to have are curiosity and the ability to learn. If you combine these two, then there is a whole world out there from which you educate yourself. You don’t have to go and sit in a stuffy classroom and listen to some academic lecturing. Don’t get me wrong: academics are hugely valuable. It is just that you don’t have to join a university to engage with them.

Three chapters about things I will try to do from now on:

Embrace constraints (page 67)
This chapter starts as follows:

“I don’t have enough time/money/people/experience.” Stop whining. Less is a good thing. Constraints are advantages in disguise. Limited resources force you to make do with what you’ve got. There’s no room for waste. And that forces you to be creative.

This is a principle that I am already highly aware of (it is actually embedded in every introduction to any Parallax post on this blog). It is not something I am naturally good in though. I love gadgets and these things often create a lot of extra affordances and thus complexity. I need to tone this down to allow a better focus on things that really matter. First step: “downgrade” my current Ubuntu 10.04 setup which allows me a lot of flexibility (and gives me wobbly windows, that’s not me by the way) to the Ubuntu Netbook edition.

Focus on what won’t change (page 85)
This is probably advice that anybody tasked with working on innovation should heed to. Naturally we like to be focussed on the next big thing. The danger is that you will focus on fashion instead of on substance.

The core of your business should be built around things that won’t change. Things that people are going to want today and ten years from now. Those are the things you should invest.

I will try and use this advice while thinking about the next iteration of our learning landscape. Which aspects are lasting needs and wishes and which are just fads?

Interruption is the enemy of productivity (page 104)
I work in an office with about 10 other colleagues (if everybody is in). During a working day I receive about 50 emails in my work Outlook inbox and have multiple instant messaging conversations. This means that I barely have a couple of minutes without any interruptions. I have to admit that I am probably the cause of many interruptions too, as I constantly share the things I find fascinating or funny with my co-workers.
This is definitely not beneficial for my ability to do work on things that require a bit more concentration and need me to be focussed. It takes a lot of time to write anything which is more than a page of two for example. Usually I can only do it if I work from home and I turn Outlook off. From now on I will try to block a couple of hours every week during which I will sit by myself, turn off my phones, IM and email, refuse to look at Google Reader and just work.
It is as the authors say:

Your day in under siege by interruptions. It’s on you to fight back.

Three chapters about things I wish my employer would do going forward:

Meetings are toxic (page 108, available in the free excerpt)
This one is pretty obvious, but we still have a complete meeting culture. Everybody knows that meetings are not very effective at what their intent is to do and still we have way to many. Some of the reasons the authors give for why meetings are this bad are:

They usually convey an abysmally small amount of information per minute

They require thorough preparation that most people don’t have time for.

They often include at least one moron who inevitably gets his turn to waste everyone’s time with nonsense

Meetings procreate. One meeting leads to another meeting leads to another…

If you still need to have a meeting I like their simple rules:

Set a timer. When it rings, meeting’s over. Period.

Invite as few people as possible.

Always have a clear agenda.

Begin with a specific problem.

Meet at the site of the problem instead of a conference room. Point to real things and suggest real changes.

End with a solution and make someone responsible for implementing it.

I think we are especially guilty of inviting too many people to meetings and I would love to meet at the site of a problem instead of a conference room, but am not sure how this is done with IT related issues.

Don’t write it down (page 164)
We spend an inordinate amount of time capturing everything everybody says, needs and wants. We have hundreds of Excel files containing lists of requirements, feature/enhancements requests, issues, etc. We probably spend more time managing these spreadsheets than working on the issues that these spreadsheets are an abstraction of.

There’s no need for a spreadsheet, database, or filing system. The requests that really matter are the ones you’ll hear over and over. After a while, you won’t be able to forget them. Your customers will be your memory. They’ll keep reminding you. They’ll show you which things you truly need to worry about.

Don’t scar on the first cut (page 260)

The second something goes wrong, the natural tendency is to create a policy. “Someone’s wearing shorts!? We need a dress code!” No, you don’t. You just need to tell John not to wear shorts again.

This is how bureaucracies are born according to the authors. They consider policies “organizational scar tissue”. I work for a company that, like most other I am sure, is very scarred. Let’s all stop scarring it more!

I have to admit that a list of three was severely limiting when it came to wishes for my employer. I would have like to have the opportunity to add: Ignore the real world (page 13), Illusions of agreement (page 97), Hire managers of one (page 220) and They’re not thirteen (page 255).

5 Things I Cannot Live Without

Arjen Vrielink and I write a monthly series titled: Parallax. We both agree on a title for the post and on some other arbitrary restrictions to induce our creative process. For this post we agreed to write about things we cannot live without. The restriction is that the things should have a hierarchical relationship where the lowest level of hierarchy is the microprocessor and the highest level is the Internet. Each thing should be described in 100 words. You can read Arjen’s post with the same title here.

Please don’t take the title of this post too literally: yes, even I realise that I will be able to live without these things. Instead consider this a tribute to these five things. Also be aware that the title is not “The 5 Things I Cannot Live Without”, there are many other things that I find way more useful and crucial (think bed, dishwasher, etc.).

So here goes, in a loose hierarchy from local to global:

1. The Microprocessor
What do you know about the microprocessor? If it as much as I used to, then it will be very little! Did you know that the first microprocessors appeared in the early seventies and that they were mostly used for calculators? Did you know that their capacity follows Moore’s law? Did you know that microprocessors not only integrated in computers, but also in cars, toasters, TVs, dishwashers (again!) and most other electrical equipment with some advanced functionality? Finally, did you know the Wikipedia article for Microprocessors needs additional citations and references? Why don’t you get to work and fix it?

2. My iPhone
I don’t think I have yet waxed lyrical about my iPhone. First of all I am late to the party: I have only bought one last December. This is because I resisted buying a closed down Apple product for as long as possible. I really really wanted to buy an Android phone, but all the ones that I tried were seriously less capable than the iPhone. So why is it that much better? Because thought has been put into every single element of the software and hardware design. Nothing is accidental, everything is considered. No other company is there yet.

3. Xs4all
My Internet provider is XS4ALL. There are a couple of reasons why this will be the case for the foreseeable future (even though their price/speed ratio is not competitive):

XS4ALL is consistently the best provider in the Netherlands.
Their corporate values and activism are excellent. See this campaign for an example.
They have repeatedly shown they have a backbone. Their support of Karin Spaink in her Scientology case is the best example of this.
Innovation is important to them.
When you call their helpdesk (at a number which has normal rates), you get competent staff.

4. Google Services
Over the last couple of years I have come to rely more and more on Google’s services. So much so that it has become increasingly hard to even list all the Google services that I have an account for or use regularly otherwise. As an excercise I have used this Wikipedia page to list all the products I use regularly (on Ubuntu or iPhone): Chrome, Sketchup, Gears, Calendar, Gmail, Product Search, Reader, Apps, Feedburner, Youtube, OpenSocial, Maps, Aardvark, Alerts, Translate, Groups, Image Search, Scholar, Web search, Analytics, Gapminder, Trends and Zeitgeist. Couldn’t be bothered to link them all: Google them!

5. The Internet
It is a cliché to call the Internet a “game changer”. However, it cannot be denied that it is the most disruptive technology out there. It creates feasibility spaces for social practice (thank you Benkler) and it forces you to rethink traditional ways of doing things. In the field of educational technology for example it has led to, among other things, new course paradigms, an Edupunk movement and deep critiques of the learning function. We cannot fathom what the near future of the Internet will look like as the pace of change is continually accelerating. I cannot wait for it!

P.S. This post was inspired by Techcruch’s Products I Can’t Live Without.
