I told you all I was going to be No. 1, and I did just that.

I never single out any one competitor. I treat all my rivals equally.

I don't have a clue. These things don't bother me. I think about the technical stuff but not how many steps or what my heart rate is.

Racing comes easily to me, especially the 100 metres. That is why, no matter how fast I run the run the 100 metres, the 200 will always mean more to me, because of the effort I've put in.

When people contact me on Instagram or Facebook, kids and adults, who say, "You're an inspiration. You make me want to work hard to achieve my goals." If I can still do that after I retire that makes me feel good.

For me, time is everything, because from the time you wake up you have to have your heart and soul in this. You have to work through the day, you have to go to the gym, you have to eat, and yet you have to work as fast as possible to get home and get rest before the next day begins again.

You can't really give away anything in your book ... should be exciting, it's my life, and I'm a cool and exciting guy.
