Adequately prepared? Yes, absolutely. If I hadn't studied music there I wouldn't be a 42R Band Musician in the Army, I'd be an 11B Infantry.

Thing is though, there is no guarunteed success in music. Lots of people drop out, lots of people change career paths, hell even I might.

All I have to say is that the people who end up being successful in the arts are not necessarily the most talented, they're just the ones too stubbern to do anything else. After a decade of living in poverty they look around and see that all the competition has found a better paying job in sales and that they are the only ones left in town qualified for any of the art jobs.

Be diverse and learn as much as you can. You don't have the luxury to say "Oh I'll play this but I'll never play that." You have to know how to play your instrument, AND how to write, AND how to record, AND how to book gigs, AND how to manage finances, AND how to lead others, AND how to set up a PA and a drum kit even though you will never once sing into a mic or play the drums. I sure as hell never knew how to play the bass, but I had the opportunity and I said yes, and that path ended up taking me to some pretty cool places. If you approach things now with the mindset that I need to invest now and learn as much as I can so that in 10 years I will be as useful as I can, then you will succeed.

When you love your passion enough, sacrifices will be made. I had to leave my band, my friends, my girlfriend, a beautiful city that I love, and go through some shit at basic, just so I could play the sax. I know that I could earn a lot more money and have it way easier doing something else, I just can't do anything else.
