TEACHING

The best way to understand something deeply is to explain it to someone else.

The internet rewards people who teach. If you know something well enough to explain it simply, you have a business.

We have 200,000 courses because we believe the best teacher for any topic is someone who just mastered it, not someone with a PhD who forgot what it is like to be confused.

I cleared the UPSC exam at 22 and became an IAS officer. Then I quit to teach on YouTube. Everyone thought I was crazy. Now millions of students learn from me daily.

I still teach classes personally. The day I stop teaching is the day PhysicsWallah stops being PhysicsWallah.
