For me, it's important that a fan can buy something that is related to me. Like in soccer, you buy a shirt and it's got somebody's name on the back. That's kind of a cool thing.

I feel a bit awkward playing in a red shirt out at Wimbledon. But I don't dislike it.

When you're good at something, make that everything

Watching a movie a couple of weeks ago. An American movie. I can't remember the name, but it wasn't even a sad movie. It caught me off guard. I was on an airplane.

I had a nice dinner. I let the evening unfold, flow. I like to sit in a chair with a wine glass. When I woke up, I thought, 'Why didn't I go to bed at 11?' I came back at 3 and went to bed at 5.

I don't mind fans coming up in a friendly, respectful way. That's all part of the fun of being a top tennis player. But if people take pictures without permission, particularly if my children are in the shot, I feel uncomfortable.

Confidence? Are you kidding me? I mean, please. Look, some players grow up and play like that. I remember losing junior matches. Just being down 5-2 in the third, and they all just start slapping shots.
