I get my drive and determination from just winning and playing tennis. I know if I don't work, I won't get rewarded. It was a life long dream to win a Grand Slam so when I was able to do that it felt so good and I wanted to do it again. It's not that hard to stay motivated.

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.

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 all tennis players have to struggle through the early stages of their career. We start off playing tournaments and really just get by. I always had a dream to play in the big tournaments and never have doubted if it was worth it. Having to battle a little early on in my career makes it all the more worthwhile now.

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.

My workouts include aerobic exercise for a healthy cardiovascular system; strength training to maintain muscle tone and bone density; core strength exercise for a stable mid-section; and stretching to maintain mobility.
