Before me, sprinters retired at 23 or 24. I run because I still like it, I can make a living, and I feel I was born to do it. And because people tell me I can't do it.

I always want to be the best and if I can't, I don't want to run.

I want it all. Fame, fortune and all the commercials there are to do.

I can feel the wind go by when I run. It feels good. It feels fast.

I was single-minded and I had tunnel vision. Now it's time for a change.

I am thrilled to be 31, still running and having my daughter watch me even if it is on TV.

I can't run forever. I decided to go back to school for my degree, because I know now there's more to life than track.
