Matches are won and lost so many times in the locker room.

Everyone has to call 'time' at some stage.

I feel like when I'm match tough and match hard and played a lot of matches I got that competitive winning spirit going and I can get on some rolls like I did last year. I won San Jose, Indian Wells and made the semifinals in Miami so it can happen for me.

Oh, I get pretty fired up on the court. I try to play with a lot of emotion, especially when I'm playing in front of a large crowd. I want to go out and do my best, and to do that, I have to play with the most energy possible.

Grand Slams are funny things. You have to try to find a way to get through the first week and put yourself in a position in the second week. A lot of strange things happen.

My video game character is a bit better looking than me, actually. I don't think he has to worry about his hair getting messed up.

When I was a kid in Adelaide, I dreamed of becoming No. 1 in the world, winning a grand slam and the Davis Cup for Australia.
