Stay healthy, do sports and above all have fun while doing sport. Competing or just for fun, whatever, simply enjoy and try your best. Working hard, working well with achievable goals normally pays off. Believe in the people that are with you and listen to those who have more experience.

You fight, you try your best, but if you lose, you dont have to break five racquets and smash up the locker room. You can do those things, but when youve finished, nothings changed. Youve still lost. If something positive came from that, I probably would do it. But I see only negativity.

However great your dedication, you never win anything on your own

I have the same bedroom I've always had. It's clean and tidy when I get home, and after two or three days it gets messy and my mother nags me.

For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.

There are many moments during a match when you are tense, wrestling with yourself. Tennis is a lesson in self-control.

I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.
