Daniel, my big brother, is eight years older. I'm lucky he didn't mind hanging out with his little sister and my younger brother.

I think I will always stay involved in tennis and would like to give back by helping out young players. I have done a little commentary and may one day enjoy doing that again.

In tennis it's easy to get greedy - and one Grand Slam doesn't feel enough any more.

You've just got to get over that mental hurdle and those battles in your own head during matches when things aren't going so well. It takes time. It's probably all things I already knew, but for someone to talk about it maybe in a different way makes you realise things.

I started mountain-bike riding two years ago, which is much better than riding a stationary bike in the gym. Mountain biking is a total body workout.

People think that there is so much money in tennis, but the reality is unless you're ranked in about the top 50 you don't earn much at all. It is hard to support yourself travelling the world, to be away from home most of the year and to pay for a coach to help you become a better player.

Control the things you can control .
