'm so fortunate to have done what I love to do for so long, but the day I retired was one of the best days of my life. Not because I was happy to get away from the sport, but because it was clear in my mind that I had done all I possibly could, and that it was time to go.

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

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.

To this day, most people think of me as the fastest human. They don't really think me as a long jumper, although that's the event I had more success in.

Life is about timing and overcoming difficult things.

I tell you, it was kind of two-fold. I fortunately had a lot of support. My coach was amazing - he told me to focus on being prepared and that is what I did. Every athlete is nervous - any athlete who tells you they're not nervous isn't telling you the truth. I was as prepared as I could be.

Channel your energy. Focus.
