A man 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.

I don't know whether war is an interlude during peace, or peace is an interlude during war.

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

All the great pleasures of life are silent.

When a man asks himself what is meant by action he proves he isn't a man of action.

A man's life is interesting primarily when he has failed - I well know. For it's a sign that he tried to surpass himself.
