"Your mind is not your friend, Mike… you have to fight with your mind, control it, put it in its place. you need to control your emotions.
Fatigue in the ring is 90% psychological. It’s just the excuse of a man who wants to quit. The night before a fight, you won’t sleep. Don’t worry, the other guy didn't either. You’ll go to the weigh-in, he’ll look much bigger than you and calmer, like ice, but he’s burning up with fear inside. Your imagination is going to credit him with abilities he doesn't have. Remember, motion relieves tension. The moment the bell rings, and you come in contact with each other, suddenly your opponent seems like everybody else, because now your imagination has dissipated. The fight itself is the only reality that matters. You have to learn to impose your will and take control over that reality" - Cus Damato Quote to Mike Tyson
