When I decided to go for four gold medals I planned it out over a few years. It was in four different events and there was a lot to it.

I never competed against athletes. I competed against perfection.

When I run - you can see my record - I run to win.

The best kids are going to become the best. But the best thing about it is that you're going to learn lessons in playing those sports about winning and losing and teamwork and teammates and arguments and everything else that are going to affect you positively for the rest of your life.

I've found that a person does not need protein from meat to be a successful athlete. In fact, my best year of track competition was the first year I ate a vegan diet.

My thoughts before a big race are usually pretty simple. I tell myself: Get out of the blocks, run your race, stay relaxed. If you run your race, you'll win... channel your energy. Focus.

Track and field is the best way to reach out for kids. It doesn't matter how fast you are. You always want to beat someone.
