Sleep is extremely important to me - I need to rest and recover in order for the training I do to be absorbed by my body.

Yeah, I am lazy. There's no doubt about that.

It's a great feat for me to have broken my world record.

I don't like losing anyways.

If you think about racing too much you may just lose it a little bit.

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

I wouldn't say I'm a phenomenon, just a great athlete.
