I set out to learn bass -- my first-ever musical instrument -- in my early 40s (about 20 years ago). My only goal was to get good enough to be in a hobby band in which I was welcome and could hold my own. I succeeded at that and am now in two such bands. I couldn't be happier. I'm probably not "good enough" to be in a lot of bands, but I don't care: I'm good enough to do what I'm doing, and honestly couldn't care less about what I might or might not be able to do otherwise.
