Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.

I had to know at least two languages.

I think if you do not enjoy your time, your life, if you do not live intensely and do not spend time with your family, in one way or another it will be reflected in your career.

In order to stay where I am - and I want to do that - I have to stay dedicated as well as I have been before I became No. 1.

I have been through two wars in my 24 years, and I know what it's like to be without anything, to see the bombs flying above your head.

I never wanted to change countries; it's something that is part of me.

Nothing, nothing, nothing is better than sex, it is what God created us to do.
