If you want to learn faster, teach what you know. It sounds counterintuitive, but this simple switch from passive consumption to active explanation is the secret weapon for rapid, durable learning.

Meaning
The core message here is that the act of teaching isn’t just for the benefit of the student; it’s the ultimate hack for the teacher’s own understanding.
Explanation
Here’s the thing I’ve found after years of applying this. When you just consume information, you’re building a shaky scaffold in your mind. You think you get it. But the moment you have to explain it to someone else, you’re forced to confront all the weak spots, the gaps in logic, the things you only vaguely understood. It’s like your brain goes into a different mode—a construction mode, not just a storage mode. You have to structure the information, find simple analogies, and anticipate questions. That process, that cognitive heavy lifting, is what truly etches the knowledge into your brain. It’s the difference between recognizing a face and being able to draw it from memory.

Origin & Factcheck
This specific phrasing comes from Timothy Ferriss’s 2012 book, The 4-Hour Chef, published in the United States. While the concept itself is ancient—often traced back to the Roman philosopher Seneca who said “While we teach, we learn”—Ferriss packaged it for a modern audience focused on accelerated learning and meta-learning.
