To some people the ego is evil. It gives you so much. It gives you everything you want. But it takes back too much in return. It gives you everything: money, riches, women, glamour, everything you want. But in return it takes back so much, and you're soulless. That's its goal. The ego's goal is to leave you soulless.

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.

Nothing is more humbling than getting your ass kicked.

I earned that the strong will always beat the weak, but the smart will beat the strong. Boxing is a tough guy sport. But in the end, the tough guy gets to clean the streets and be a bodyguard. In the ring, the tough guy is going to get hurt; at the end of the day, he's going to talk funny. Only the smartest win. So, I know it's cliché, but power - real power - comes from knowledge, comes from smarts.

I'm just a guy that is basically depending on my responsibility skills. I'm really responsible with my children and my wife and my family life. Things have changed with me. I'm not a night person anymore. I've got too many responsibilities to play.

I guess I'm going to fade into Bolivian.

I don't want my kids to be like me, I don't want my daughter to date a guy like me. You know, for a guy like me success is to take care of my children to take care of their life and make 'em cushioned. I don't want them to be around people like me. You know, success for me would be that they never have the opportunity of being in the presence of someone like me.
