The serve, I was too young and too small and... not enough powerful to have a good serve when I was young, so my forehand was always my signature shot. So I used to always run around my backhand, you know, use my forehand as much as I could, and so that's why I think it's my strength also today, you know.

What I think I've been able to do well over the years is play with pain, play with problems, play in all sorts of conditions.

I have two lives, and all the problems I might have, I feel like I drop them once I step on to the match court.

Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

My advice is you've got to make sure you wear the clothes and not [let] the clothes wear you. It's quite simple in a way. Don't wear something you totally feel uncomfortable with, but take some chances. Play around a bit. I felt very uncomfortable in suits when I was younger, so what I just started doing was wearing suits when I was going to dinner. I used to overdress a little bit so I got used to wearing suits. Now wearing a suit is like wearing a track suit for me. So it's all good.

One should just be able to play a perfect game.

The more I lose, the more they believe they can beat me. But believing is not enough, you still have to beat me.
