Kostya Tszyu quotes:

It's all about one split-second. Boxing is a funny thing. You blink your eyes and somebody says good night to you.

If you want nothing, do what you want. If you want everything, develop discipline

When somebody can be intimidated, I use this. Because I'm very wise person. I know how to intimidate my opponents. I know how to play tricky stuff for them.

When we go in the ring we know we're going to get hit. We know we're not the ballet people. But if you go in there and have doubt in your mind that you're afraid to get hit, forget it.
