Booing - I never like it. We see it in other sports all the time, but in tennis, it's rare.
Every good tennis player has to have a short memory. Good or bad.
I had a lot of success in big tournaments as well - won Masters Series in Rome - so a lot of things are coming together. I've done a lot of hard work in the off-season. A lot of physical work, a lot of work on my serve and on my return game.
Me and my brother are players that spend three to four hours in the gym every day doing running, lifting heavy weights, and doing treadmill stuff.
I think it's normal that, the first time you meet Federer or Murray or Djokovic, you're going to get nervous. But after a while, they become normal opponents, people you see every week. That's the way you have to think. You can't think of them as legends. When you see someone on court, you have to treat every opponent the same way.
I've been shadowing my brother since I was a little kid. Maybe that helped me feel more comfortable with the big guys.
