" Every athlete who has pushed beyond his or her known limits of endurance in the quest for improvement understands these sentiments. There is no experience quite like that of driving yourself to the point of wanting to give up and then not giving up. In that moment of “raw reality,” as Mark Allen has called it, when something inside you asks, How bad do you want it?, an inner curtain is drawn open, revealing a part of you that is not seen except in moments of crisis. And when your answer is to keep pushing, you come away from the trial with the kind of self-knowledge and self-respect that can’t be bought. "
