My whole outlook on life is, never judge a book by its cover.

You name him. I beat him.

I know that there's a god because I was able to survive everything that I've been through - all of the tough times - and I'm still at the top of my game.

When you talking boxing, you talking me.

You have to protect yourself at all times. What goes around comes around.

Most people should be talking about how Floyd Mayweather is a great undefeated future Hall of Famer that's his own promoter and that works extremely hard to get to where he's at. Instead, all you hear is hate and jealous remarks from critics who criticize me and, you know, most of the time, the people that criticize me can't do what I can do.

A lot of times, in the beginning of my career, I put pressure on myself just because I wanted to perform so well. I just wanted to be perfect.

I'm not here to judge Mike Tyson. I'm not here to judge nobody. I'm not here to monitor no other fighters. I respect him for what he did in the sport of boxing. He was an entertainer.

I got a granite chin.

We talk about these legendary fighters, talk about how they had hundred-something fights, hundred-something victories... but when you look at the history books, I still beat more world champions than any fighter in history.

I'm not here to judge. We don't know what Trump can do.

Well, you've got certain obstacles that get in your way throughout your career, but you have to be a strong individual.

You've got to have a villain and they'll always make me a villain. I'm used to it - it makes me work harder and it makes me fight harder.

When no one knew who Dana White was... Dana White used to run around with me, hang out with me, and I treated him just like anyone else in my camp.

Boxing is real easy. Life is much harder.

You know, as a young child, I lay in my bedroom and I swore to myself then: 'I'm not going to smoke and I'm not going to drink.' And I said I'm not going to just say that when I'm a kid. I'm going to stick to that as an adult. I kept that in mind my whole life.

There comes a time when money doesn't matter.

I want to be promoted in the urban areas. A lot of African-American people should know more about me.

Once I am in the square circle, I am in my home.

I feel like everybody is against Floyd Mayweather. I don't get any respect.

Some people are just right for you.

When I step in the ring, I bring everything I have.

Ali was a threat because he was a voice, and the people hated Ali when he was a voice, but once Ali could no longer speak and he wasn't a voice, they loved him. Love me now. I don't want to be loved if I could barely walk or barely talk. That's not cool.

Self-preservation is an important thing to me.

Boxing's in my genes. I come from a fighting background. My dad and both my uncles were good boxers. I'm blessed with the art of war.

You hear certain things, negative things, all the time that aren't true, but you never hear about the positive.

I think my grandmother saw my potential first. When I was young, I told her, 'I think I should get a job.' She said, 'No, just keep boxing.'

Mike Tyson was one of the fighters who motivated me. How? We both used to train at the Golden Gloves boxing gym. I used to see his Rolls-Royce, his diamond Rolex on, and I said, 'You know what? Those are the things that I want.'

My dad was in a hospital for months. The doctors told my dad he would never be able to walk again. My dad beat all the odds. He came back and was able to walk and start boxing again. He went to No. 1 in the world at welterweight to fight for the world title. But he never had his chance to fight for a world title.

I turned pro as a 20-year-old, won a world title a year later, and remained a world champion ever since.

For Conor McGregor, I'm coming out of retirement just to fight Conor McGregor.
