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.

Step 2 will uncover some gaps in your knowledge.

This step involves going back to studying, reviewing it with an intense focus on these gaps. The aim of step is to remove these weaknesses and turn them into areas of strength.

It's like how watching a movie more than once helps you spot more details, look from different perspective and improves your understanding of it.

Ideally, you've already made significant progress in your understanding of the desired skill. But you're not done yet. Now you need to simplify the content.

This step is quite successful in helping you develop a solid understanding of a topic. It is quite challenging to be able to break through the noise and explain things in a way that even young children with minimal vocabulary can understand. When you try to achieve this, you are forced to truly understand the knowledge or talent as well as understand how all of the different components work together.
