Receiving the Newcombe Medal for a third year in a row is an amazing honour. The Newcombe Medal is a great occasion for the Australian tennis community to come together and celebrate our sport, recognise people's achievements and contributions to Australian tennis.

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.

Tennis is all about mental toughness, and you have to keep your head in the game. I make time to relax away from competition pressures, travel and intense training schedules to make sure I'm looking after myself. Taking time out with family and friends helps to maintain the work-life balance everyone needs.

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.

I think Serena Williams is the best tennis player of this generation, if not the best ever. It is amazing for her to be playing as well as she is at the age of 31.

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.
