Good post (only repeating a partial quote from it) and very relevant. I thought I was the only one thinking that same thing!
It's fine to have a hobby pickin' and grinnin' but you must be realistic about your talent (or lack of) and realize that it most likely will NOT be marketable, but it can be enjoyable.
I play banjo and some fiddle but no, I don't think there's anyone that'll PAY to listen to me but my old hound dog "sings" with me if I break out the fiddle. I don't plan on quitting my day job...
A good day job.
. . . my husband is an excellent guitarist on an electric, and quite good on classical. He substitutes in a couple of bands when their guitarist is unable to make it, and he's a regular at a local classical guitar benefit. I play the piano and harpsichord and fool around with the guitar. We both sing in the church choir.
Neither one of us has any illusions about being able to earn a living in music!
