Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever.
– Lance Armstrong
The time your game is most vulnerable is when you’re ahead, never let up.
– Rod Laver
If you aren’t going all the way, why go at all?
– Joe Namath
