It's always a wake-up call to get beaten.

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

I can still improve a lot, but there is definitely a limit to what the human body can do.

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.

When I'm at the gym, I think about chicks, going to the beach, and looking good. I do it for the girls.

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

I know what to do and I go and execute.
