Congrats !!!!!
I have very little doubt that you couldn't be successful in the music industry. You ave the skills and seem to have the ambition and work ethic. However, the pay is bad, the hours are terrible and the benefits are both positive and negative, but suck as far as insurance and shit like that you will want when you start a family or get sick. I would keep a good back-up plan available if I were you.
Brain surgeon and rocket scientist take a little too many years in college so that is ruled out, but both the medical and technical fields are good fields. Being a musician means you have skilled hands. A mechanic/electrician/welder/industrial technician etc.) or nurse (male RNs can make a killing) might be something to think about. However, it usually takes three to four years to become an RN now and two years to become an electrician, welder or mechanic and three to become an industrial technician.
I'm not trying to tell you what to do, but I thought I might give you some suggestions.
