My shoulder's not where I want it to be, but I'm doing a good job of monitoring it.

A great tennis career is something that a 15-year-old normally doesn't have. I hope my example helps other teens believe they can accomplish things they never thought possible.

I'm not a huge gym person, so I try to stay away from the gym. But I love to run on the beach or go for a walk. It's better than riding a stationary bike.

I hit a ball for a living, but I have that passion to keep learning.

I learned there's a big difference between juniors and the pros.

It's always tough when you lose - you've worked so hard for that moment and it hasn't gone the way you wanted. But you have to realise there's always a bright side, you have to pick yourself up and get ready for the next game.

Sometimes when you're putting the work in it just seems so, so hard, and you never know when that work's going to pay off.
