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.

I have sometimes played my best Davis Cup matches away from home when you stay in the moment a bit more. But it is tough when half the crowd are spitting on you.

I'm fortunate: I can play as long as I want to play. There's no coach or trainer who is going to say to me that I'm dropped or sacked, it's time to move on. I can play as long as I want to play.

Even when I was No. 1 in the world, I was taking it one match at a time. I never was a player to look too far ahead, the way draws can pan out.

Maybe if you're playing in London or America, you don't feel that pressure quite as much.

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.
