At her birthday, my seven-year-old daughter will say that she wants these big cakes and certain expensive toys as presents, and I can't say no to her. It would just break my heart. But when I was little, for birthdays we just played outside and we were happy if we got any cake.

My fines? I pay more fines than some guys' career prize money on the tour.

The trouble with me is that every match I play against five opponents: umpire, crowd, ball boys, court, and myself.

While I didn't have everything that I wanted, I was still a happy kid.

I just try to play tennis and don't find excuses. You know, I just lost because I lost, not because my arm was sore.

Winning Wimbledon was a great feeling and it is still a great feeling. It has given me so much confidence.

If I can't serve on grass, I can maybe help cut the grass, paint the lines and serve some strawberries.
