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.

Emotion is more than just anger. When I am performing, I need emotion, but I need control, too. Emotion drives the best performance and is necessary, but it must be controlled. I believe Fedor [Emelianenko] does that. I do too. We may look different in how we do it, but we both do it.

Even though I heard him say he doesn't believe, cuz' that's why from watching Ali gave me the great deal of confidence and deep-down inner belief to believe there's no man fighting that could beat me.

I'm scared every time I go into the ring, but it's how you handle it. What you have to do is plant your feet, bite down on your mouthpiece and say, 'Let's go.'

On stage it's just a wild setting - we have a big screen - hecklers, I'm fighting. It's entertainment, but I want to pierce [the audience's] souls and have them think about what I have to say.

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.

In the scheme of life, in emotion and loss, I responded the way I did. I lost. I shouldn't have responded that way. I've had some people tell me that I did a great thing - sticking up for myself - but to me, personally, with the way that I handled my emotions, I lost. But I learned. That will not happen again.
