I'm here to serve God and be of service. I'm nothing; everything out here is a lot bigger than me.

I'm the biggest fighter in the history of the sport. If you don't believe it, check the cash register.

What really amazed me was when I sent a suit out for cleaning, forgetting that $700 was in the pocket. They sent the suit back to me. If that happened in New York, both money and suit would be gone.

I was blessed with speed and a good punch. Everybody thinks I'm the hardest puncher ever. But I just think I was really fast, and my punches got to the target faster. That's what made my knockouts always seem spectacular.

We all have to control our feelings. That's the thing that separates us from animals.

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.

Ten years ago, if you asked me where I'd be now, I'd have said F-ing dead. But I'm not dead. I have an awesome life. And I'm just very grateful. That's the one thing I try to convey. Gratitude.
