WWant to learn something new? With the coronavirus spreading across the globe and forcing us into a state of self-isolation, now is as good a time as any. And there’s no shortage of low-cost or completely free resources you can access from the comfort of your couch: online courses, podcasts, videos, and e-books.

To inspire you on this journey of self-education, I’ve gathered all the best resources I know of. I’ve also made a list of some specific topics you might like to indulge in, and I included a few tips on the best ways to learn. Let’s dive in.

How to learn

Build your second brain

Watching and reading interesting stuff is a great start. But have you ever tried to explain or talk to someone about what you’ve learned, and found yourself struggling to remember important details or explain it with much coherence?

Good notes will help. By jotting down simple notes as you explore the material, you’ll have a basic structure of the important ideas, which can help jog your memory at a later time.

There are lots of places to find tips for note-taking — here’s a good example from Forte Labs. Or you might consider reading How to Take Smart Notes by Sönke Ahrens.

There are also many digital tools available: Evernote is popular, and even the basic Notes app that comes with Apple devices does a decent job. I’ve recently become a big fan of Notion, which I used to put this article together.

Tiago Forte, who runs Forte Labs, refers to all the notes that you collect and organize as your second brain. When well constructed, this second brain should make information easy to find and give you the ability to connect ideas into larger concepts.

It’s a great idea and a great metaphor. But I also want to stress that as helpful as another brain can be, it’s never going to be as easily accessible or as fast as your first brain. So while taking and organizing notes is an immensely valuable activity, ideally you want to store the important stuff between your ears.

Transfer to your first brain

The best way to tell if you remember something is to actively try to recall it. Recalling doesn’t mean looking back over your notes — rather, it means looking back into your memory and seeing if what you want is in there.

While many of us have lingering test anxiety from our high-school days, tests really are beneficial learning tools. The funny thing is, testing ourselves doesn’t just reveal what we do and don’t remember — it actively strengthens the memories. When you fail to remember something, and then follow up by finding the answer in your notes or online, that act of trying means you are more likely to remember the right answer in the future. Psychologists have called this the testing effect.

A simple way to apply the testing effect is with flashcards. Transfer your notes to an app such as Anki or Quizlet, and test yourself every so often. If you leave some time between when you first learn something and when you study it, you’ll find you’ve forgotten parts of it. Don’t worry — a little forgetting is actually a good thing. It means you’ll put more effort into your attempted recall, enhancing the testing effect.

Spread your knowledge to other brains

You may have heard that one of the best ways to learn is to teach. Teaching means putting some skin in the game: The feeling of concern that someone might criticize your ideas forces you to more thoroughly evaluate them.

Not only do you have to remember, organize, and express these ideas in your own words, but you expose yourself to feedback and questions, which can open up new avenues for further learning and refining. Simply having a conversation with someone will do, but if you want to get creative, you can try writing an article, recording a video, or designing an infographic.

There’s a lot of information out there, and even if you’re not saying anything entirely new, there’s always that possibility that your interpretation, your creation will be the first time someone else encounters that idea. That could make a big difference to that person. You might inspire them to learn more, to talk about it with others, and help spread it even further. The world is awash in information, but good ideas are always worth passing on.
