Life is often compared to a marathon, but I think it is more like being a sprinter; long stretches of hard work punctuated by brief moments in which we are given the opportunity to perform at our best.

Examine the opportunities, the challenges you've given yourself.

The only thing you can never change is your values.

As an athlete, I was never really comfortable with being a celebrity.

It is important that you strive for humility, but not humiliation, for a cool, level-headed confidence, not a stiff, delusional arrogance.

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.

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