Rivalries don't necessarily mean races being close at major championships. I had a rivalry with Butch Reynolds for many years. I won all the races, but Butch was the world record holder before I came into the sport, he was extremely talented and he was the only other man running 43 seconds.

The basis of self-discipline: Don't allow the edges to blur.

The only way to deal with loss - as a horribly unwelcome guest that you know will show up eventually. And so you deny it and reject it and ignore it and laugh in its face. You toss it out into the street and push it away and fight it off, and only it has landed square in your lap, only then do you deal with it.

The mind is absolutely instrumental in achieving results, even for athletes. Sports psychology is a very small part, but it's extremely important when you're winning and losing races by hundredths and even thousandths of a second.

You learn as much from those who have failed as from those who have succeeded.

Your problems pale in comparison with those of the millions of people in the world who do not have enough to eat.

You owe it to yourself to find your own unorthodox way of succeeding, or sometimes, just surviving.
