I rarely post as I know you don't like advice but I had a brief story that I thought might interest you. You will probably think it won't apply to you but so did he.
I was at school studying music at your age. One day I was in an orchestra playing Haydns trumpet concerto. The soloist was one of the other students. Like all of us he partied and liked a drink to steady his nerves. This one night though he lost it on stage in front of a packed audience. He couldn't get the notes, he panicked it got worse. In the end we had to abandon the concerto half way through the first movement. He didn't get any more chances. Music is not a forgiving world. You have to be at the top of your game and whilst brass players are notorious for being the ones to have a drink over here go too far and your career will be over before you start.
I know you probably think this has nothing to do with you so feel free to ignore the post if you do.
