It's very hard in the beginning to understand that the whole idea is not to beat the other runners. Eventually you learn that the competition is against the little voice inside you that wants you to quit.George A. Sheehan
I have self-doubt. I have insecurity. I have fear of failure. I have nights when I show up at the arena and I'm like, 'My back hurts, my feet hurt, my knees hurt. I don't have it. I just want to chill.' We all have self-doubt. You don't deny it, but you also don't capitulate to it. You embrace it.Kobe Bryant
