I try to focus and compete and do positive things for the sport.

I try to lead by example.

I'd like to say to all my fans out there, thanks for the support. And to all my doubters, thank you very much because you guys have also pushed me.

I don't listen to music before a race - my coach doesn't like it, he thinks I might lose my focus and concentration.

If I can stay [involved] with the sport, we can find different ways to motivate people and preach to them and explain to them that all they need is dedication to the sport.

There is no stress. I live my life, I enjoy it and when I am comfortable I can get married.

Rihanna, Beyonce and Nicki Minaj - we may not win, but we would have a lot of fun [in 4x400m relay team].
