Now if you are going to win any battle you have to do one thing. You have to make the mind run the body. Never let the body tell the mind what to do. The body will always give up. It is always tired morning, noon, and night. But the body is never tired if the mind is not tired. When you were younger the mind could make you dance all night, and the body was never tired...You've always got to make the mind take over and keep going."
- George S. Patton, U.S. Army General and 1912 Olympian
