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

The age of 40 is not a death sentence.

If you can look in your mother's eyes and she's proud of you, then you're a champion.

When I found Jesus Christ, I learned to be a better athlete. I didn't have to go out there and knock them out in the first round. I've learned to be patient, skillful in the ring. At the same time, I wanted to prove to other boxers that you can take off this killer instinct stuff, you can be a great athlete, a great boxer, and love your brother.

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.

Let the other guy have whatever he wants before the fight. Once the bell rings he's gonna be disappointed anyway.

People trust me. I sell sincerity.
