If all you are wishing for is a career in music (a range of jobs wider than most) then that's what you'll get. Or you'll fall short and be disappointed or just burn out. I used to want to be a pro saxophonist. That led to study (much outside of my interests), taking any old gig, doubling (or attempting to) and just finding myself in less than inspiring musical situations all the while thinking I was doing the right thing. I was moving so far away from what initially attracted me to it all. I would have been better off painting or doing parkour since they would have been closer to the original mode of creativity. I'd just try or investigate everything in an around music (from teaching to post and further into the tech end) and figure out what things work for you and what doesn't. Completely non-musical work makes up much of it while other jobs outside of music may be closer in some ways.
