The Rope a Dope would not have existed without the Big Dope.

I hit Ali with everything and he said 'is that all you got' and I said 'yeah, that's pretty much it.'

Sonny Liston stood up to me and actually made me give ground. No one has ever done that to me before or since.

Don't try to reinvent the wheel. Just learn from the guys who have already done it well. You need a mentor, a seasoned coach who is willing to share his wisdom and experience with you. Ask someone who has already been successful to guide you.

You live and learn. Then you die and forget it all.

You never help others by allowing them to getaway with giving less than their best efforts.

I'm the world heavyweight champion. I consider myself a citizen of the whole world.
