No doubt about it, in my career Ron Lyle hit me the hardest. One time he hit me so hard I didn't see it until I saw it on film when I woke up!

To be successful in life, you must get in the habit of turning negatives into positives.

They say I don't fight guys unless they're on a respirator. That's incorrect. They have to be at least 3 days off a respirator.

There's more to boxing than hitting. There's not getting hit, for instance.

You have to keep your goal in mind and never lose sight of it. I envisioned myself winning the heavyweight title for ten years before I actually captured it. If you're not driven to do your best, you'll never reach the level of excellence in your life.

You may have even an ex-wife or an ex-husband, but you can never have ex-children.

Anybody going into boxing already has brain damage.
