For me, there's a lot of expectations and you want to be able to live up to them.

Being a role model is a privilege.

I think every genius person has a bit of insanity.

For me, my faith is the reason I run. I definitely feel I have this amazing gift that God has blessed me with, and it's all about using it to the best of my ability.

I always look back to my first Olympic medal in 2004 in Athens. I was very new to the sport, and it was my first big win at the Olympics.

I try to think about my goals. I think about my competitors-I know they're working hard, and if they are, I have to work hard too. I have to be one step ahead of them.

Jackie Joyner-Kersee is actually someone I have a personal relationship with and who continues to do amazing things in her community. I continue to be inspired by her. If I can emulate myself after someone it's her and I just hope to have that effect on my community and continue to go on to do things like she has.
