I don't care about anything I don't need to care about.

One of the reasons I got into this game was because I wanted to learn how to get myself comfortable in uncomfortable situations. I grew up in a tough area of Dublin, and fighting was just part of your life. Boys fight, and I won some, but I lost a lot too, and I didn't like that, I didn't like that feeling of not knowing whether I was in danger, in trouble.

I have unemployed my girlfriend. She had a job working for a cardiologist and now she can hang out, put her feet up, buy all the things she wants, have a nice breakfast with you and me in the Four Seasons. Any fights in families like mine come from everyone worrying about money. I'm taking all those worries away. That makes me feel happy, makes me really proud of what I do.

I used to imagine it. I used to pretend that my Peugeot driving to the gym in the rain in Dublin was a Ferrari on the Vegas strip. And now that I have that? I can't even describe that feeling. That's why I like the best - the best cars, the best food, the best watches.

The surface below your feet is so special. It is not like a boxing ring, not like a wrestling mat, it's its own thing, and when I am there, I am floating, I am moving with total freedom, I am free. And when you know, when you just know you are going to win, like I do, there is no better feeling.

There are people who have great skills, who do great things, but don't embody the whole animal that is the fight game like I do.

A fight is mental, not just physical and psychological warfare is absolutely part of that.
