When you are young, you are a little naive.
I have a Russian heart.
I'm just a very tough person when I go on the court, and I really don't want to lose.
It's pretty hard being a tennis player and Mother Theresa at the same time and that's just the way it is.
No matter what you study, the thing that you know best is what you grew up with.
My main goal is to stay healthy because when you're injured you realise how lucky you are to have your health.
