you cant quit rock and roll, its in your soul, sometimes you have to pull back from it for a bit to find yourself but the mojo will come find you
I hung up my bass at 30 figuring I'd given rockstarhood my best shot and missed,
got real successful doing video shows for other bands
ten years later I had had enough of the toxic circus of playground politics that showbisness is at the pointy end and started a new life as a care worker working in a local special needs school,
one of the jobs I got given was helping a lad teach himself guitar
5 years later the school has grown, i run the music department and spend my Fridays getting paid to play and using Otis reading and nirvana to help kids who cant make eye contact with each other co-ordinate together to rock out
and its the best job I've ever had
my point is, if you're deep enough into music in the first place, quitting is just kidding yourself. it'll come back knockin on that door
