I don't think that a leader can control to any great extent his destiny. Very seldom can he step in and change the situation if the forces of history are running in another direction.
At one point I had to shove as much food in my body as possible to pack on calories. My trainer wanted me to do six meals a day and not go two hours without eating. If I would cheat on eating one day I could tell - I'd drop a few pounds.
