Muhammad Ali

I do need publicity but not for what I do for good. I need publicity for my book. I need publicity for my fights. I need publicity for my movie but not for helping people. Then it is no longer sincere.

If Ali says a mosquito can pull a plow, don't ask how. Hitch him up.

This life is not real. I conquered the world and it did not bring me satisfaction.

Maybe I was great in the ring, but outside of boxing, I'm just a brother like other people. I want to live a good life, serve God, help everybody I can. And one more thing. I'm still gonna find out who stole my bike when I was 12 years old in Louisville and I'm gonna whup him. That was a good bike.

To the people that have said I'm too small, I'm not fast enough, I don't have what it takes, I'm not strong enough. THANK YOU

I'm the greatest thing that ever lived! I'm the king of the world! I'm a bad man. I'm the prettiest thing that ever lived.

Eat your words! Eat your words! I am the greatest.

I'll leave you with one that I have hanging on my office wall, compliments of Nike: Impossible is nothing.

Stay in college, get the knowledge. And stay there until you're through. If they can make penicillin out of moldy bread, they can sure make something out of you. Advice to a young person to continue his education.

True success is reaching our potential without compromising our values.

When it comes to love, compassion, and other feelings of the heart, I am rich.

God tries you in certain, certain ways. Some people are rich, and they believe in God. They lose the money, things get hard, they get weak and quit going to church. Quit serving God like they did.

The word 'Islam' means 'peace.' The word 'Muslim' means 'one who surrenders to God.' But the press makes us seem like haters.

Once the Choice is Made, Do Not Look Back, Do Not Second-Guess Your Decisions

I’m young, I’m handsome, I’m fast, I’m pretty, and can’t possibly be beat. They must fall in the round I call.

Joe Frazier got hit more than me - and he doesn't have Parkinson's.

Some gems for the greatest of them all

Age is whatever you think it is. You are as old as you think you are.

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

Only a man who knows what it is like to be defeated can reach down to the bottom of his soul and come up with the extra ounce of power it takes to win when the match is even.

Every day is different, and some days are better than others, but no matter how challenging the day, I get up and live it.
