Who are your heroes?

My heroes are my mom and dad because they really support my career and I appreciate that.

Is there a book or movie that has changed your life?

My worst day ever was when I saw the price of the yo-yo that I wanted to buy. . . it cost $200!!!

What would you be doing if you weren’t doing this?
