An athlete and actor are really two different temperaments, night and day. As an athlete you really keep things out and as an actor you really bring things in.

At the end of the day, if you're a professional athlete in track and field you are the CEO of your company.

My best year of track competition was the first year I ate a vegan diet.

Countries like Jamaica do not have a random program, so they can go months without being tested. I'm not saying anyone is on anything, but everyone needs to be on a level playing field.

People have a moral standard about what they will do and will not do. At the end of the day someone who cheats has a lower moral standard than someone who does not. And they will cheat in other areas of life as well.

I'm a fast learner. I may not run as fast as I used to, but I think I still learn as fast.

The trials on the road to world harmony are no greater than the courage of those who accept the challenge.
