If you are not making mistakes, you are not trying hard enough.

Once you learn to quit, it becomes a habit.

I would say that the quality of each man's life is the full measure of that man's commitment of excellence and victory - whether it be football, whether it be business, whether it be politics or government or what have you.

Character is the direct result of mental attitude. I believe that character is higher than the intellect. I believe that leadership is in sacrifice, in self-denial, in humility and in the perfectly disciplined will. This is the distinction between great and little men.

Winners never quit and quitters never win.

There's no such thing as Perfection. But, in striving for perfection, we can achieve excellence.

Relentlessly pursue perfection knowing we won't catch it, but in the process we'll achieve excellence.
