Never put your money against Cassius Clay, for you will never have a lucky day.

If you lose a big fight, it will worry you all of your life. It will plague you - until you get your revenge.

A rooster crows only when it sees the light. Put him in the dark and he'll never crow. I have seen the light and I'm crowing.

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

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

Life is a gamble. You can get hurt, but people die in plane crashes, lose their arms and legs in car accidents; people die every day. Same with fighters: some die, some get hurt, some go on. You just don't let yourself believe it will happen to you.
