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.

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 love to get home and hang out with my family. My brothers and I love spending time at the beach. I enjoy doing all kinds of surf sports and keeping healthy.

Control the things you can control .

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 did always dream of being a professional player. I think every kid does dream of being a pro, but to last the journey you have to love tennis as a sport and if you are lucky enough to make it in the pros, it is really a bonus.

You're the best in the world, so you deserve those little perks along the way if you can get them.
