“I ain’t never nervous. Never nervous.”

I think I already proved that I wasn’t just fighting for the money, because I fought as an amateur. I fought 90 fights for free.

I push myself to the limit.

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

I’ll back up anything my dad says.

Every home that I have is paid for, every car that I have is paid for, and I am a hundred-million-dollar man. I mean, this is the truth; it’s not a lie.

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

People have said things about me, and wrote and criticized me about things in the past, but it goes in one ear and out the other.

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.’

I’m always focused.

Everything people say I couldn’t do I’ve done.

I haven’t took no punishment. There’s nothing cool about taking punishment.

Worry about going out there and making your own legacy.

There comes a time when money doesn’t matter.

When I was about 8 or 9, I lived in New Jersey with my mother and we were seven deep in one bedroom and sometimes we didn’t have electricity.

I’m just an American dream.

In the end, you have to protect yourself at all times.

It is important for me to feel at home.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don’t dislike it.

Regardless of how you feel inside, always try to look like a winner.

Even heartbreak can find a way to feel like home.

Don’t follow any advice, no matter how good, until you feel as deeply in your spirit as you think in your mind that the counsel is wise.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

What I believe is this: Catalunya is not Spain, it is something else and you have to feel it.

To hurt is simply an act of remembering. Of holding my skin to the edge in the hope I might feel anything at all.
