This is quite in-depth, pretty good.
Unrelated to the Khan Academy.

Ciro feels that this resonates a lot with his OurBigBook.com.
Supercut:
The minute I dropped out I could stop taking the required classes that didn't interest me, and begin dropping in on the ones that looked far more interesting.And much of what I stumbled into by following my curiosity and intuition turned out to be priceless later on.Because I had dropped out and didn't have to take the normal classes, I decided to take a calligraphy class to learn how to do this.If I had never dropped in on that single course in college, the Mac would have never had multiple typefaces or proportionally spaced fonts.Of course it was impossible to connect the dots looking forward when I was in college. But it was very, very clear looking backward 10 years later.Again, you can't connect the dots looking forward; you can only connect them looking backward. So you have to trust that the dots will somehow connect in your future. You have to trust in something — your gut, destiny, life, karma, whatever. This approach has never let me down, and it has made all the difference in my life.
Then:
You've got to find what you love.Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work.And the only way to do great work is to love what you do. If you haven't found it yet, keep looking.So keep looking until you find it.Don't settle.

When I was 17, I read a quote that went something like: "If you live each day as if it was your last, someday you'll most certainly be right."
And then he quotes form the Whole Earth Catalog, a paper Atlas from the '70s he admired:
Stay Hungry. Stay Foolish
Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page. View it live at: ourbigbook.com/go/topic/derivativeVideo 2. OurBigBook Web topics demo. Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control

You can also edit articles on the Web editor without installing anything locally. Video 3. Edit locally and publish demo. Source.
