2. Teach

Once you’ve completely covered the topic, it’s time to teach it to someone else.

If you’d rather avoid actually teaching someone, you can just teach it to an imaginary audience. But the Feynman technique works much better if you use a real person. They’ll be able to give feedback and let you know when something isn’t clear.

Ideally, the person you’re teaching will ask questions and probe you, trying to find holes in your knowledge base. This might feel a little uncomfortable, but it’s exactly what you need in order to improve.
