Sometimes God gives instructions that go against conventional wisdom, such as treating people kindly when they're hateful. Who really wants to do that? Instructions like that may not always make sense, so that's why I need to trust and obey the One who inspired them.

Klitschko has had a good career. A lot of his fights have been out of the country as though he hasn't even been invited into the real heavyweight picture in the United States. He's a good fighter. You can't talk about him unless you can beat him and it doesn't seem that there's anyone around who can truly beat him.

If you don't dream, you might as well be dead.

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.

A Jack Russell terrier? My god. He'll burn you up. They never stop. A German shepherd, you can only go so many miles.

Anybody going into boxing already has brain damage.

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.
