When you teach what you learn, you’re not just helping others. You’re locking that knowledge into your own brain, effectively doubling your ability to remember it. It’s a powerful, active way to learn.

Meaning
The core idea is simple but profound: the act of teaching isn’t just an output of your knowledge; it’s a powerful input mechanism for your own memory.
Explanation
Here’s the thing I’ve seen over and over. When you learn something passively, it sits in a shallow part of your mind. But the moment you have to explain it to someone else, your brain has to work differently. You have to organize the information, simplify the concepts, and find the right words. That process—that mental heavy lifting—forges much stronger neural pathways. It’s the difference between just seeing a map and having to draw the map from memory for a friend. The latter forces a deeper, more durable understanding. You’re not just repeating; you’re reconstructing, and that’s where the magic happens.
