Richard Feynman was arguably one of the most impactful scientist of the 20th century.
His learning technique goes like this:

Pick something you want to learn about

• Teach it to a 10-year old - or pretend to

• Identify knowledge gaps

• Fix your knowledge gaps

• Rinse and repeat until you're confident in your abilities

You wouldn't believe just how many times I thought I'd understood something, only to later struggle to explain it in simple terms.

Lesson learned ha!
