It means a lot; I always love to represent my country, and it's an honor to be part of the Olympics and be with other athletes.
Living out of a bag, in hotels, packing, unpacking, travelling, the hours of flying, sometimes the credit card doesn't work at the hotel, or the room isn't ready - I'm lucky to have a team around to help me.
It wasn't very easy getting used to being famous. Everybody stared at me in the supermarket and on the street. I think my life changed, for sure.
I don't do any exercises when flying but use compression socks and spend as much time as possible lying down. I try not to eat much - I'm not a fan of airplane food; everything is just so weird.
One thing I always do is listen to my iPod. I listen to whatever is kind of new on the radio, I am always downloading stuff.
You can feel up, you can feel down, and you have to keep your emotions kind of somewhere to be focused on the next ball.
I'm going to try to put less pressure on myself, but I know how easy it is to say that rather than to feel it, but that's how it is.
Of course it's one of my goals to win another grand slam. Wimbledon was great - so if it's Wimbledon again, that's fine - but I think I have the game to win the other grand slams as well.
If I had to choose between a third Wimbledon title and the number one ranking, I would choose Wimbledon. The ranking just shows how you're doing in the year, so I think the Slams are first, and it shows in the number anyway.
