I use to think that way but did the family thing and my purpose until these kids grow up is work to put food on the table and a roof over their heads.

after they're grown up and out of the house, THEN maybe I'll figure out what I REALLY want to do.

As for the OP being a janitor and volunteer - well buddy, from how I see it looks like you have a good work/life balance. If I had some kind of trade like you do, oh yeah, I would love to use it and live a simpler life than the corporate bs I have to go thru in my daily office job.
