I have had lots of luck in my career but there has also been a lot of hard work.

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

When I'm down or maybe when it's close in the match, I feel like I'm still in it. I don't feel like I'm letting down. Mentally, I'm still really, really tough.

I've been very competitive by nature from a young age, whether it was eating a bowl of pasta faster than somebody else, or always wanting to be the first one in line.

I don't get to do as much sightseeing as I would like to.

My style when I was younger was still unique to me. I didn't necessarily dress by the trends, but I was always aware of what was trendy at the time and how I could apply it to my own sense of style.

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.
