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

I admire Roger Federer, not only for his tennis but also for his personality.

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

It was different when I was young, aged 20, playing the French Open. I didn't have so much experience. I just played tennis because I loved the game.

If I make a change to a young kid to play any sport, not only tennis, instead of spending time in front of the TV or computer, that is good. I want to give them a good example: 'Hey, go out and play and see the world.'

I work out a lot, but it changes day to day. I always start out with some cardio - either a jog, a bike ride, or footwork drills designed specifically for tennis movement. Then I do weights, but I switch the days: one day it's upper body, the next day it's lower body. Then I do stomach and back pretty much every day.
