The main concept of the book is that you should spend and develop yourself. And the first thing you're talking about is how I can get this without charging anything haha.
The author told his whole staff they needed to make 50 sales calls. Then he told them they needed to make the calls in 30 minutes. He went and made 28 calls in 22 minutes. The point is to stop analyzing and paralyzing yourself with overthinking. Just act.
