“I’ve been in that situation many times before – where I’m losing and I have to knock a guy out.”

I wanted to start in boxing, but you have to train a little harder to be a boxer. A lot of those guys can take punches. MMA, you only have to hit someone so hard to knock them out.

I’ve been in deep waters a bunch of times in my fights.

You eat salad and you’re hungry the next 30 minutes and you’re hungrier from when you ate the damn salad.

I speak my mind too much, and the UFC probably don’t really like that. But I really don’t care.

I just feel that all the top fighters in the world are making all the money.

This heavyweight division, it takes just one punch for anyone. It doesn’t matter how hard you train or what.

I don’t even train for these fights. I’m not mad when people say that because it’s true.

I just believe that my heart is the best in the sport. And I believe that’s what carried me through my whole career. Not my talent or my power or anything like that. I just believe my heart.

I’m just going to keep fighting, try to stay active as much as possible.

I’m fighting just so I can take care of my family.

I don’t care where I’m at in the heavyweight division. As long as I win enough, so they keep me. That’s about it.

I have a lot of anger built up in me from my childhood. My wife and kids are the only ones who give me peace in this world.

I know just about everything that really goes on with domestic violence.

Brock Lesnar is not a fighter. He’s scared to be hit.

A lot of people said I would never make it, and this and that, I’d never be a top 10 fighter, that I’d never fight for a title. Just stuff like that. Achieving all those goals and being the person that I am, this is going against everything everyone said I couldn’t do.

I always had dreamed one day Bruce Buffer’s going to be introducing me. Derrick ‘The Black Beast’ Lewis and I just always pictured him saying it.

At various points, in big ways and small, we get knocked down. If we stay down, grit loses. If we get up, grit prevails.

You gave me the key to your heart, my love, then why did you make me knock?

What anxiety means is it’s as though the world is knocking at your door, and you need to create, you need to make something, you need to do something. I think anxiety, for people who have found their own heart and their own souls, for them it is a stimulus toward creativity, toward courage. It’s what makes us human beings.

Opinions are like belly buttons; everybody has one. I never knock a man for his opinion.

When suffering knocks at your door and you say there is no seat for him, he tells you not to worry because he has brought his own stool.

I think you just have to keep knocking down doors, you have to keep being aggressive, and even if somebody says ‘No’, then you have to knock on the next door.

Things seem to take so much longer for me to do. I have to say things 10 times instead of once. I have to knock on 10 different doors instead of two. For everything.

We don’t have storm troopers that just knock on the door of every American citizen. We don’t do that for any crime. But when we have evidence that a particular person has committed a crime, we send law enforcement to apprehend them.
