Learning by Teaching
Deepen understanding by preparing to teach others.
Explanation
The act of teaching forces you to organize information clearly, anticipate questions, and fill gaps in your understanding. Even if you never actually teach someone, just preparing to teach dramatically improves your grasp of the material. Teaching reveals what you thought you knew but actually didn't.
Real-World Example
Before teaching presentation skills, you think you understand it. While preparing, you realize you don't know why some techniques work. You research the psychology, practice examples, anticipate student questions. Your understanding deepens 10x through the preparation process.
How to Apply
Choose a topic you want to learn. Prepare to teach it to someone specific (friend, colleague, imaginary student). Create an outline, examples, and practice explanations. Anticipate questions and objections. If you can't explain it simply, you don't understand it well enough yet. Actually teaching someone is even better, but preparation alone improves understanding significantly.
