It was different when I was young, aged 20, playing the French Open. I didn't have so much experience. I just played tennis because I loved the game.

All we see is gym, tennis court, and bed.

I used to always want to play the perfect match, and this meant not losing a point. The realisation came around the time I was 19 years old, in the French Open final in 2007. This was a key period in my career. I was told I was going for too many winners, which was affecting my game.

I admire Roger Federer, not only for his tennis but also for his personality.

If I make a change to a young kid to play any sport, not only tennis, instead of spending time in front of the TV or computer, that is good. I want to give them a good example: 'Hey, go out and play and see the world.'

When you have tough times, and when you learn you can't be perfect in every situation, it's hard to accept, you know, because I still do expect that. But you just have to, because, you know, it's not about the situation. It's how you deal with it. You always have a choice.
