I agree with getting older/having kids makes you less selfish, but don't you have to be selfish somewhat in order to believe in yourself? I concur that some choices are more suited to some folks than others. I'm envious of people who have found happiness in the family thing... Not jealous, just glad they've found their magic elixir I suppose...I didn't say non paying crap gigs cause I've never done one nor will I ever. Not sure of your "gig" situation but I've never had trouble finding or being found for gigs.
People make their own decisions based on their life choices at that given moment. If your good at what you do you can make it both work. 30 years ago I was much younger,dumber and a bit selfish. I've changed since then and spend much more time with loved ones while still gigging non crap gigs.
Regarding MY gigs...
I've had some REALLY bad ones and some ridiculously good ones!
