When I was young, I didn't really think about anything other than sports.

I know what I can do so it doesn't bother me what other people think or their opinion on the situation.

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.

You have good days and bad days.

I remember when I was 14, I went to race in Hungary, and I went to a concert, and they were playing Bob Marley songs, and I thought, "Wow, this guy is so special." It's Marley every time.

A few people have said I should let you win

I want to be one of the greatest athletes ever to live, not only in track and field, but in all of general sport.
