As I'm not a professional, this question may not be aimed at me, but I'll give it a shot.
Everything I've read about standard contracts, royalty payments, and other business practices of the music industry has made me glad that I'm not involved with it. There was a time that I wanted to become a rock star, even a very specific time when, but for a single choice, I might have actually launched a career; but the man I am now is of the opinion that the man I was then dodged a bullet.
I seek out other creatives to find ways in which my work and theirs will mutually benefit. I'm looking in multiple directions to find ways for the music to find its audience, even as I rearrange my life to give the music a larger role in it.
And, mainly, I play, and let the music suggest what I should do with it.
