I always say that in order to appreciate warm weather, you must experience cold. I wouldn't change one thing - all the embarrassing moments, the defeats, all of everything - through all of this, I have learned me.

I've been knocked down more than any heavyweight champion in history.

I've learned so much, so very much about myself in defeat. I've learned very little to nothing in victory.

For if you train hard and responsibly your confidence surges to a maximum

It's easy to do anything in victory. It's in defeat that a man reveals himself.

When you have millions of dollars, you have millions of friends.

Cassius Clay must be beaten and the Black Muslims' scourge removed from boxing.
