Playing music I like with people I can get along with is the main thing. I'd add that the band has to at least do something, be it record or certainly play live but that is basically it for me. I'm not massively driven by finances or a quest for fame. I think I've succeeded in that in 25yrs of playing I've always done what I set out to do, albeit with any desire for it to be a main source of income long gone.
