Some of us are happy doing what we have been doing for many years, and others wish they had taken a different path. I am a musician and have done this only as a hobby for years (and my real careers have been mundane but steady) and I wish I had gone on a self-funded tour of several states. One friend of mine did this only for a year, another for five, and one for twenty and was able to call it a career and did way better than pick up debt or just break even. The latter, of course, was way better than I could have ever been and it was interesting to hear of all the famous people he backed up on stage and in the studio. I never quite had the courage to do this but a couple of fellow small town musicians I knew embarked on this expensive lifelong dream and in every case before they got married or had kids. I got married early and also felt an obligation to mirror in life what I did in school (which in my case was about being marketable and safe instead of interesting).
