I don't need to come back to Wimbledon every year because I can't live without it. I'd be totally cool without tennis.

Mentally, I'm not ever going to go away.

Tennis can be a very frustrating sport. There is no way around the hard work. Embrace it. You have to put in the hours because there is always something you can improve. [Y]ou have to put in a lot of sacrifice and effort for sometimes little reward but you have to know that, if you put in the right effort, the reward will come.

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.

I don't mind fans coming up in a friendly, respectful way. That's all part of the fun of being a top tennis player. But if people take pictures without permission, particularly if my children are in the shot, I feel uncomfortable.

A man who wins, is a man who thinks he can.

My family is the thing I miss most on the tour.
