At 16, I was busy being a kid. I think some, not all, musicians who want to be great let their instrument take over their life and it just isn't healthy. I went to school with some great players but they had no life outside of that instrument. Do yourself a favor and strive to be better each time you pick up the trumpet but do not let it consume you. In today's world kids are pushed and rushed along at anything they excel at but are burned out before they reach their full potential. Don't worry so much about where you are, as where you want to be and how to get there without beating yourself up.
