“We’re the only animal that wakes up and doesn’t stretch.”

I want to be financially secure by the time I have kids.

At 155, I will be the same animal, an even better animal.

People think hard sparring will get you sharp. And you do get sharp in the gym. But anytime I’ve trained that way, I’ve actually been a little bit flatter in the fight. And the knockout shot hasn’t come. It’s almost because my training has been too hard.

I certainly would not like to end up in a tie-up with Ms. Rousey.

Everything I’ve been thinking, every vision, even down to every shot I throw, it just ends up here in reality.

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

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.

People think I’m a celebrity. I’m not a celebrity.

We come bulletproof in Ireland. We’re reared tough, and we fight.

I’ve learned new footwork patterns that are very unusual. I’ve learned how to find a lower centre of gravity, and I’ve found more angles to throw shots.

I have the greatest job in the world. I get paid loads of cash for beating the crap out of people. And I’m very good at it.

I never got into training to be an All-Ireland boxing champ or to win a belt. At the start, I just got into it to learn how to defend myself when I got into situations.

Not a lot of people or pros in this game know how to train correctly. That’s why they don’t have a long career. Their body gets banged up. They get into a rhythm of heavy sparring and heavy work, but through that, they’re limiting movement.

What can I say? I’m a talker.

I see fighters make funny videos about me and stick them on Facebook and get 20 likes.

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.

Only 4 percent of all the companies owned in Scotland have their head offices in Scotland.

The only way to learn is for it not to get a laugh, so you can adjust it and come back the next day to see if it’s working right. Next time, you might get a different laugh. You’re constantly rebuilding.

To be Catholic is the only way of being fully and utterly Christian.

We are not created only to enjoy the world, we are created in order to evolve the cosmos.

I’m a Buffalo wing magnet, a sandwich fanatic, a cheesesteak guy. But I’ll only get a cheesesteak in Philadelphia. No one else does it right.

My advice to teens is to try and do something that scares you every day because it’s the only way you can test how far you can really go.

I would love to slip into the skin of a fish and know what it’s like to be one. They have senses that I can only dream about.

Success can only come to you by courageous devotion to the task lying in front of you.
