I think people go through a crisis in their mid to late 20s over this, I know I did. I busted a gut from my teens until I was 2 trying to "make it". For me I got married and felt pressure from me to grow up. I'd done all the gig bookings, flyers, promotion etc and all my bandmates had houses and better jobs. I stopped for 5 years where I got both a house and a better job. I started playing for fun again at 32yrs old. Over the last 8yrs this fun has seen me sign an Indie deal, get primetime US TV coverage of the band, international radio play, tour the country and get rave reviews in the UK National music press for the last two albums. I think concentrating on my playing and having fun helped me much more than trying to make it. For me at least. I don't expect I'll ever make a full time living from it (2 bandmates do due to teaching & session work) but I'm happier with where I am.
