Right on! Without a clear idea of what you want to do, you need to understand that the most important thing about the music industry is that CONNECTIONS ARE EVERYTHING. I was 19 and making $1500 USD a week. I had no degree. All I had: A few friends in the industry that told a management firm that I was a good tour manager and it would be a smart idea to hire me. Continue with your schooling but understand that just having a degree isn't going to get your too far. You need to network! Get invited to a party where some people in the industry might attend? Even if you fucking despise parties, please attend. If you're 21, start going to bars where people in the industry might hang out. If you're not in a place like NYC, LA, Chicago, or Nashville, try to find places that local venue promoters will be hanging out. Get in with them and try to get in on guest lists to shows then try to become friends with smaller touring bands. Let them sleep on your couch. That's how I ended up touring. Understand that people in the industry need to have MASSIVE trust in who they are working with. My first paying tour management job was with an artist that I had never met before. Hell, I didn't even actually meet his management until about a week into the tour. They basically just trusted me into handling thousands of dollars a night.

TLDR; Networking with industry people is the key to getting your foot in the door.
