Discipline makes hard men. Every hard man is capable of being a killer. But every killer is not capable of being a hard man. They can't endure that much. It's all about the endurance. That's why they become killers. Because they can't endure the pain. They need to kill the pain to stop it.

Fighting is all about calmness and relaxation. My appearance was all an illusion. My appearance is of a mad man, but I'm really calm and collected. Even though I'm fighting, I'm calm and relaxed as possible, despite my displays, because once you get excited, you can't fight at the highest level of your ability.

To be successful in sports or business, you really have to live the lifestyle. Success is about lifestyle. Just because I was training and working hard, that didn't make me champion or a good fighter. My lifestyle made me a good fighter. In my mind and my daily life, I was the heavy weight champ when I was 15 or 14. I lived the life of the heavyweight champion, and that's who I became. And that is so much more than just training. So, when the time presented itself, that's who I already was. I was ready. I was already there.

I'm addicted to perfection. Problem with my life is I was always also addicted to chaos. Perfect chaos.

When I go to Europe or South America, they laugh at things that are totally different than what Americans would laugh at. It's just so crazy how we're so different in personalities with other people.

I paid a worker at New York's zoo to re-open it just for me and Robin (his wife). When we got to the gorilla cage there was 1 big Silverback gorilla there just bullying all the other gorillas. They were so powerful but their eyes were like an innocent infant. I offered the attendant $10,000 to open the cage and let smash that silverback's snotbox! He declined.

I guess I'm gonna fade into Bolivian.
