I've worked dozens of different (and usually very physical) jobs in my teens and 20's - from lumberjack to farmer to painter to working warehouses and eventually working security.
My 30's I've spent working desk jobs in call centers - started on the phone and ended up a part of workforce management. Funny because I hated math and never could figure out Excel, but I spent my days staring at Spreadhseets...
I found comfort in the idea that I could earn enough to support the both of us working from home, and that I had the best "real job" I could ever hope for, considering my lack of any formal qualifications.
Sporadically, I'd play live or write for documentaries or video games...
When my wife signed with Cirque, we decided that there was no option other than me following her. I started writing music for her, recording her demos and being the male equivalent of a housewife. (I'm a "houseband" I guess).
We finally settled down here in Vegas and were recently approved for the green card. So I'll be able to get a social security number and work. We hope to start our own business but I should be mostly working from home, part time, in the studio. We have tons of project. And a couple of live music projects.
