“A man who waits to believe in action before acting is anything you like, but he is not a man of action. It is as if a tennis player before returning the ball stopped to think about his views of the physical and mental advantages of tennis.”

“Be proactive. Begin with the end in mind.”

“You do not rise to the level of your goals. You fall to the level of your systems.”

“I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.”

“If you don't like something, change it. If you can't change it, change your attitude.”
