Doubt is only removed by action. If you're not working then that's where doubt comes in.

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.

Real champions fight through adversity.

I am in the fighting game, I don't care about anything else. I don't watch the news, I don't care about politics, I don't care about other sports. I don't care about anything I don't need to care about. This is my sport, it is my life. I study it, I think about it, all the time. Nothing else matters.

I love money because I've earned it.

I studied every move, I became fascinated by thinking what I could have done differently. And I take that approach now as a professional. I am on it, all the time, never stop thinking, learning. You don't get to be world champion unless you do that.

I try to eat healthy all the time. I don't eat takeaways. I drink mostly water or coconut water.
