Nobody is born as a champion. You have to earn it through hard work. Get started!

Aggression means emotions. Emotions means you’re gonna get off your plan and that means you’ll lose the fight.

I should say that mental strength is No. 1, experience [is] No. 2, physical strength is No. 3, and genetic ability that you're getting from Mother Nature probably comes after.

It's not my place to compare myself to greats like Tyson, Frazier or men like that. But I would look at a fighter like Evander Holyfield. He's a great heavyweight who worked his way up through the weight classes to become champion and had to beat bigger men along the way.

The man wannabe actually...a wannabe. David Haye's a wannabe.

Mental strength is really important because you either win or lose in your mind. And I'm not solely talking about sporting matches, boxing events - anything you do, you do it first with your mental strength. And you can actually train and develop it, and I am responsible for what I'm saying because I have experience with that.

Only younger brothers will understand me. We're following in the footsteps of older brothers. You are looking up to your brother. You want to do the same things. You want to do as good as he and do it even better.
