I have to fit holidays around tournaments, particularly the grand slams, in Melbourne, Paris, London and New York.

The crowds are very important for tennis. It makes you play better, but it can also make you nervous and that's the beauty of it.

The more I lose, the more they believe they can beat me. But believing is not enough, you still have to beat me.

Once you reach a good level in tennis it fills you with a lot of motivation. I hope I can do it for a long time.

It is always in my mind still that I can crush anybody. That's not an issue. But I think that is the same for most athletes. If you don't believe you can win tournaments anymore, then you can't do it.

I always believe if you're stuck in a hole and maybe things aren't going well you will come out stronger. Everything in life is this way.

You have to believe in the long term plan you have but you need the short term goals to motivate and inspire you.
