Sometimes, the people we invest the most time in disappoint us the most.

My career has been over since 1990.

Everyone says "I wish I was in your shoes...", the hundreds of people that wish they were in my shoes don't know the tenth of it. If they were in my shoes they would cry like a baby.

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.

Fighters are never who they appear to be

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.

Emotion is more than just anger. When I am performing, I need emotion, but I need control, too. Emotion drives the best performance and is necessary, but it must be controlled. I believe Fedor [Emelianenko] does that. I do too. We may look different in how we do it, but we both do it.
