Learn like Feynman
Richard Feynman was a legendary teacher. The Feynman Method is one of his lasting legacies.
Thanks to Farnam Street's blog, we have a very succinct summary:
- Choose a concept you want to learn about
- Pretend you are teaching it to a student in grade 6
- Identify gaps in your explanation; Go back to the source material, to better understand it.
- Review and simplify (optional)
On that first step, I happen to believe that learning topics adjacent to what you already know is better than learning arbitrary topics (see: Learn adjacent topics).
Learn how to learn fast
How do we learn how to learn fast?
I can mostly only speak for myself, and even then, I know I'm not the fastest learner. But some principles come to mind, which appear to have been battle-tested.
Learn adjacent topics
When picking out a topic to learn, I think it makes a ton of sense to learn adjacent topics to what we already know, i.e. things that have moderate degree of overlap to our existing knowledge base.
I think a moderate degree of overlap is necessary. If there's too much overlap, there's little expansion of the mind that happens when we learn a new thing. If there's too little overlap, there's too big of an entry barrier into learning that new thing. Having a moderate degree of overlap helps.
