Recognize winners. They come in all forms.
You're still going to win with preparation and dedication and plain old desire. If you don't have genuine desire, you won't be dedicated enough to prepare properly.
The price of victory is high, but so are the rewards.
You never know how a horse will pull until you hook him to a heavy load.
Don't talk too much. Don't pop off. Don't talk after the game until you cool off.
Never quit. It is the easiest cop-out in the world. Set a goal and don't quit until you attain it. When you do attain it, set another goal, and don't quit until you reach it. Never quit.
