“The roughest and toughest fighter I fought was Joe Frazier.”

I’ve never let anyone talk me into not believing in myself.

The man who views the world at 50 the same as he did at 20 has wasted 30 years of his life.

Don’t count the days; make the days count.

Wisdom is knowing when you can’t be wise.

My toughest opponent has always been me.

It isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe.

The fight is won or lost far away from the witnesses, behind the lines, in the gym, and out there on the road; long before I dance under those lights.

The greater our level of understanding, the harder the tests become.

To be a great champion you must believe you are the best. If you’re not, pretend you are.

The man with no imagination has no wings.

Impossible is not a fact, It’s an opinion.

The only limitations one has, are the ones they place on themselves.

It’s lack of faith that makes people afraid of meeting challenges, and I believed in myself.

True success is reaching our potential without compromising our values.

Champions come and go, but to be legendary you got to have heart, more heart than the next man, more than anyone in the world.

Friendship is the hardest thing in the world to explain. It’s not something you learn in school. But if you haven’t learned the meaning of friendship, you really haven’t learned anything.

I love to box, because I think boxing is an art.

I’ve been boxing since I was 7 years old.

Promoters need you. You don’t need them. The boxer has the leverage, and a lot of boxers don’t know that.

My mom is the Kris Jenner of boxing.

I’m putting everything I have into my boxing career so I get everything out of it I possibly can.

I’m really into boxing. I go to a gym and I’m friends with a trainer who’s a pretty famous boxing trainer and I train with him.

I never fought, I never learned kung fu or boxing, I never went into these sportif competitions. I wouldn’t cross the ocean.

I am the biggest face of boxing right now.
