I was a professional guitarist (classical) and trombonist (ensemble and jazz) at one point. It was great and I loved it, but it took so much of my time. While I enjoy it a lot, I don't enjoy it more than my career stuff. But one pays the bills and one does not, so it is an important trade off. Once upon a time I played guitar to pay the bills and had to play over six hours a day. Was fun, but that's why I have carpal tunnel now.
