I'm very easy-going off court, but I really want to win once I'm walking on to the court.

All we see is gym, tennis court, and bed.

My goal is to be No. 1 and to win Grand Slams.

I like to have my privacy. I don't like people knowing what I do in my free time. I am also a very shy person, but I understand that people want to know more.

It's not good to stretch when you're cold. Get your heart rate up, and once you finish, take time to stretch and let your body calm down.

Once I became number one, I started working even harder. I changed my technique, but injuries started creeping in - it was a big mistake, as I was doing something right to get to that spot in the first place.
