I try my best to learn from other people's mistakes. I have a lot of respect for people who can change.

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 can inspire people on how to use money, how to get economically powerful.

When you see me smash somebody's skull, you enjoy it.

Nietzsche's my favorite. He's just insane.

I can quit boxing now and practically go into any kind of business and I'll be successful just as well as I was in boxing.

Boxing is an ego-driven sport. The idea is to not get too personal or emotional with it. You just know when it's over, it's over, and that's it.
