Tupac Shakur always wanted me to smoke weed with him, and I never did it, and I wish I did...That's my biggest regret.

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

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

My life's not tragic at all. How many guys do you know who are bankrupt and just bought a $3 million house and are getting ready to get $6 million more?

That's what people respect, the fact that I wasn't a chump that laid on his back and gave up.

My objective was to hurt the other fighters. I wanted to hurt them. I wanted to be merciless. Man, I was a wild thing. It's kind of a drug, a rush.

One minute I'm robbing a dope house. Next minute I'm the youngest heavyweight champion of the world. I'm only 20, 19, with a lot of money. Who am I? What am I? I don't even know who I am. I'm just a dumb child who's being abused and robbed by lawyers. I'm just a dumb pugnacious fool. I'm just a fool who thinks he's someone. Then you tell me I should be responsible.
