Whatever the challenge was, however unattainable the goal may have seemed, I never let anyone talk me out of believing in myself.

I am the greatest, I said that even before I knew I was.

Put yourself out on a limb, sucka, like me!

I always bring out the best in men I fight, but Joe Frazier, I'll tell the world right now, brings out the best in me. I'm gonna tell ya, that's one helluva man, and God bless him

You're not going to enjoy every minute of the journey, but the success you'll find at the end will make it all worth it.

I have a beautiful daughter, beautiful wife.They look like me, we all happy and I don't have no trouble. And I ain't that much in love with no woman to go through that hell - ain't no one woman that good.

When you can whip any man in the world, you never know peace.
