I worked my ass off to earn what I have. You have to understand, not many people where I come from get to experience this kind of life.

To do anything to a high level it has to be total obsession.

It's gone, boxing's gone. What is there in boxing? Who is there to talk about, who is there that people go, "Yeah I want to fight him?", and fans go "I wanna see that fight"? There's Floyd Mayweather, and he is 38, 39, he's maybe got one fight left. What else is there? He'll have a last fight or two and a couple of guys will get a few million dollars, but way less than I'm gonna be getting in future. This sport is getting bigger all the time, and I am making it bigger.

Power and speed aren't enough to overcome someone who is strategic, who knows what you'll do before you do it and can turn it on you; someone who is mentally engaged and combines the whole package.

I've read a lot of books on the laws of attraction, and in my home I have a big book on Muhammad Ali, which I've read, because he is like a hero of mine, but other than that, no, I'm not a big reader.

I'm not a fan of routine.

You need to be able to hit, kick, grapple, wrestle, but for me so much of this is about the mind, about feeling you are in complete control of the space around you, and you know what to do at any moment. That is a wonderful feeling, but it doesn't just happen, you have to work for it, train for it, think about it all the time.
