Aman who waits to believe in action before acting is anything you like, but he’s not a man of action. It is as if a tennis player before returning a ball stopped to think about his views of the physical and mental advantages of tennis. You must act as you breathe.

In order to act, you must be somewhat insane. A reasonably sensible man is satisfied with thinking.

A man who has to be convinced to act before he acts is not a man of action. You must act as you breathe.
