Hi Areeson,
Passion is a wonderful thing. I remember being in high school and getting passionate about music. However, I'm going to play Devil's Advocate here, because I also know that decisions made in high school can have life long consequences. The vast majority of music majors end up doing something else for a career. That's why the joke goes something like this, What did the former music major say at McDonald's? Answer, Would you like fries with that? Remembering back I also know I could have majored in a science, when I took Geology as a senior (to fulfill a lab requirement) the professor asked me if I'd be interested in majoring in it. I told him I'd be graduating soon, but that question made an impact. Instead I ended up doing a lot of sales in my career. I was pretty good at it, but not great. I'm still doing music, but I know a lot of others who had more lucrative careers who are still doing music. I would suggest you explore what's required to obtain a position in an orchestra (and how difficult it is to get a spot in any major orchestra) or how many bands don't make it big. Talk to older musicians about their experience as a professional. One thing that will probably stick out is this, nobody cares where you went to school or what you learned, they'll want to know if you can play. Are you a monster at your instrument? You have the benefit of time, you have a few years to find out if you can become a monster (apparently you're not now). Just keep in mind that's only the first requirement for success as a musician. Good luck.
