I love to hit people. I love to.

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

It's the emotional punches that you can't see that are just overwhelmingly devastating to your heart - your moral fiber.

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.

What I want to do in life is just be a respectful man and just take care of my children and guide my family in the right direction. I'm not looking to be a chairperson, I'm not looking to be ambassador or anything in that capacity.

Fear and the thought of failure . . . But we don't really know what fear is. Fear is something that we create in our own minds. Fear could be like fire. You can use it to heat you up, keep you warm, cook your food. There are so many things you can use it for. But if you allow it to go out of control, it will destroy you and everything around you.

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.
