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.

There is no difference between a hero and a coward in what they feel. It’s what they do that makes them different. The hero and the coward feel exactly the same, but you have to have the discipline to do what a hero does and to keep yourself from doing what the coward does.

There is no such thing as a natural puncher. There is a natural aptitude for punching and that is different. Nobody is born the best. You have to practice and train to become the best.

Fear is the greatest obstacle to learning. But fear is your best friend. Fear is like fire. If you learn to control it, you let it work for you. If you don’t learn to control it, it’ll destroy you and everything around 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.

Boxing is a contest of character and ingenuity. The boxer with more will, determination, desire, and intelligence is always the one who comes out the victor.

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.
