“There’s ups and downs with boxing, layoffs are part of the sport and they can either help or hurt a guy.”

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.

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

Allah is the Greatest. I’m just the greatest boxer.

It’s just a job. Grass grows, birds fly, waves pound the sand. I beat people up.

If my mind can conceive it, and my heart can believe it – then I can achieve it.

I’ll beat him so bad he’ll need a shoehorn to put his hat on.

Success is not achieved by winning all the time. Real success comes when we rise after we fall.

It’s hard to be humble when you’re as great as I am.

What counts in the ring is what you can do after you’re exhausted. The same is true of life.

All through my life, I have been tested. My will has been tested, my courage has been tested, my strength has been tested. Now my patience and endurance are being tested.
