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.

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.

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.

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.

Fear is like fire. You can make it work for you: it can warm you in the winter, cook your food when you're hungry, give you light when you are in the dark, and produce energy. Let it go out of control and it can hurt you, even kill you... Fear is a friend of exceptional people... You must understand fear so you can manipulate it.

Boxing is entertainment, so to be successful a fighter must not only win but he must win in an exciting manner. He must throw punches with bad intentions.

The hero and the coward both feel exactly the same fear, only the hero confronts his fear and converts it into fire.
