My heart is in South Africa, through my mum. My mum being from here, me spending a lot of time here as well, I feel most connected to this part of the world.

There is no way around the hard work. Embrace it.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

Success is a nice thing because it always means you've taken a step forward and it gives you a sense of pride, which in turn gives you confidence and experience-a positive circle, so to speak.

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

I had set a goal with my team to try and get back to the top of the rankings, but I never thought with the depth in the game this year that I would have been able to get it back so quickly.

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.
