Those Who Can Do, Must Teach: Why Teaching Makes You Better
"Those who can't do, teach" is wrong. Here's proof: I taught at the Data Science Club while learning myself. If I help bring a room of 60 people even 1 week ahead, in an hour, that's 60 weeks of learning value creation. That's more than a year of value from one hour. Teaching isn't what you do when you can't perform. It's how you multiply your impact.
Its a duty.
