I love money, and I love movement. I like what it has let me do for my family. I have paid off my mum and dad's mortgage, I've bought them two BMWs, they can have anything they want. I am buying a fleet of cars for myself. I have unemployed my sisters, they don't need to work, don't need to worry about a thing.

Listen, I am in the fighting game, I don't care about anything else.

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

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.

It is the most powerful submission in the sport. It is a beautiful thing. You're holding them into you, their back is on you, and you are basically choking them gradually like a boa constrictor and once you've got them, the pressure goes on and they have to submit or they are going to stop breathing. It happened to me early in my career, and I panicked, and gave in, I tapped out too early. I learned a lot from that. I learned from it, learned how to do the move better, learned how to avoid it being done to me.

I believe in working harder and putting in the time - being completely obsessed. And, yeah, I think that's life.

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.
