My success isn't a result of arrogance - it's a result of belief.

My family's lineage, we are warriors. The McGregor clan, we are warriors all through. We are famous all through the world for our fighting capabilities of all generations. So I have no doubt that's stood to me and that led me down this path and gave me what I have.

I'm not going to get somewhere and say, 'OK, I'm done.' Success is never final; I'll just keep on going. The same way as failure never being fatal. Just keep going. I'm going to the stars and then past them.

Ritual is another word for fear, manifested in a different way.

My preparation is about precision. It is a science.

That's what I do this for, to secure my family's future. I don't care about anything else. I'm able to spoil people, and that's the best thing.

I believe in believing. My coach John Kavanagh is a big atheist, and he is always trying to persuade people to his way of thinking, and I think, 'What a waste of energy.' If people want to believe in this god or that god, that's fine by me; believe away. But I think we can be our own gods. I believe in myself.

I love money because I've earned it. I won sixty G's with my first knockout - and the week before, I was collecting social welfare.

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.

Glutes are power.

The thing about the truth is, not a lot of people can handle it.

I think it's an Irish thing. We don't really care. We say it as we mean it, and you have to deal with it. The truth is the truth.

Trash talk? Smack talk? This is an American term that makes me laugh. I simply speak the truth. I'm an Irish man.

I don't feel bitterness, I don't feel anger towards anybody. Fighting is never emotional to me.

I see fighters make funny videos about me and stick them on Facebook and get 20 likes. When I make a video, I sell it to Fox and make seven figures. That's the difference.

I wish everyone well, but you need to focus on yourself. You need to stop putting your hand out. Everyone wants hand outs. Everyone wants things for free. You've got to put in the work. You've got to grind. You've got go through the struggle, and you've got to get it.

I train and I go home, and when I'm home, I think about training. That's my life every day, and that's it.

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.

Life is about growing and improving and getting better.
