I'm the world heavyweight champion. I consider myself a citizen of the whole world.

Being angry and resentful of someone is like letting them live rent-free in your head.

I think its so good for boxing when a new guy or new blood as we call it, makes a big statement.

When problems arise, you will usually find two types of people: whiners and winners. Whiners obstruct progress; they spend hours complaining about this point or that, without offering positive solutions. Winners acknowledge the existence of the problem, but they try to offer practical ideas that can help resolve the matter in a manner that is satisfactory to both parties.

The boxing promotion part is really interesting, because I got the chance to do something with my sons. They carry their own weight, and I get a chance to listen to them and see what they have on their minds. I don't have to hand out things to do, and now they have things for me to do. It's an amazing privilege to get the opportunity to work with your children.

Let the other guy have whatever he wants before the fight. Once the bell rings he's gonna be disappointed anyway.

My mother was watching on television and she doesn't want me to hurt anyone.
