Feynman Technique

• Identify the subject. Write down everything you know about the topic.
• Teach it to a child. If you can teach a concept to a child, then you're way ahead of the game.
• Identify your knowledge gaps. This is the point where the real learning happens.
• Organize + simplify + Tell a story.
