In my humble opinion, change is stupid.

No one is perfect. Everybody does stupid things.

I am a little bit more famous now, but I have [some change] in my life. I live in the same place. I have the same friends.

We'll try and be very aggressive, we'll try and speed up and change gears, and we'll see who's going to win.

My parents' divorce made an important change in my life. It affected me. After that, when I can't play Wimbledon, it was tough. For one month I was outside the world.

I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.
