When you're going through tough moments, you never know when you're going to have good moments.

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.

My main goal is to stay healthy because when you're injured you realise how lucky you are to have your health.

There's not many firsts in my career, as I have been a part of many tournaments and fortunate enough to win many.

A lot of people tell me now I'm their inspiration. They say, 'I don't play baseball,' and then they mention whatever - engineer, doctor, college student, high school student - but they're hurt because, for some reason, people feel shame about themselves or embarrassed because they are short or skinny or fat or whatever.

One night, I just woke up and I went, 'Killing Jesus.' And I believe, because I'm a Catholic, that comes from the Holy Spirit. My inspiration comes from that. And so I wrote 'Killing Jesus' because I think I was directed to write that.

I have always had a mystical attitude toward inspiration. That's my nature.

Create an inspiration board before your trip! If you're like me and love photography, food, and great experiences, chances are you have a Pinterest board filled with travel inspo.
