Pain is the purifier. Love pain. Embrace pain.
If it hurts, make it hurt more.
Let the smokers and the gluttons die... and leave the living to us who know how to use it.
If you die, I will bury you in the sandhills with all the other runners.
I'm not interested in athletics, I'm only interested in achievement. Fix your goal and work for it.
Thus I urge you to go onto your greatness if you believe it is in you. Think deeply and separate what you wish from what you are prepared to do.
