I have just accepted certain things and it makes it easier. I accept I will get injured. I accept I cannot win every race. I work hard to decrease the chances of those things happening but I accept they will happen. A lot of people don't accept it. They get injured, they go crazy.

Worrying gets you nowhere. If you turn up worrying about how you're going to perform, you've already lost. Train hard, turn up, run your best and the rest will take care of itself.

I know what to do and I go and execute.

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

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.

Women always find you out when you lie. Always. No matter what, they always find out. They're like detectives.

My diet is much better. I eat what I have to. The older you get, the better you get at making sacrifices.
