Mike's (Tyson) punch is like an atomic bomb in that it is relative to nature. Both have no value unless you have a means of conveying it to the target. He is boxing-smart.

To see a man beaten not by a better opponent but by himself is a tragedy.

Heroes and cowards feel exactly the same fear. Heroes just react to it differently.

Greatness is not a measure of how great you are but how great others came to be because of you

If you can hit your opponent with two punches, you don't hit him with one. Get off with some bad intentions in there. Believe in yourself. A guy can feel it if you don't believe in yourself. Set your mind to make yourself do it.

I believe nature's a lot smarter than anyone thinks. During the course of a man's life he develops a lot of pleasures and people he cares about. Then nature takes them away one by one. It's her way of preparing you for death.

Every fighter that ever lived had fear. A boy comes to me and tells me that he's not afraid, if I believed him I'd say he's a liar or there's something wrong with him. I'd send him to a doctor to find out what the hell's the matter with him, because this is not a normal reaction. The fighter that's gone into the ring and hasn't experienced fear is either a liar or a psychopath.
