Well... I've never really had a 'real' job, in the 9-5 sense. But I've always loved what I do, "gigging" around (ie: Playing for weddings/funerals, church events, holiday musicals, high school/community musicals). I can't really complain about the hours, but I can complain about the stupid things people do at/for their weddings

.
My 'payroll' job that I have while in-school is orchestra set-up, and that is much less pleasant. Basically, 3 days a week I set up the chairs, stands, podium and occasionally the piano for the symphony. It doesn't pay that well ($8/hour, but I only work at most 9 hours a week, if there's a concert during the week) and it involves heavy lifting, plus I have to deal with wind players complaining about what kind of chairs they want, conductors telling me to set up risers and change the layout of the orchestra, and everything is within fairly strict time limits.
The only reason I stick with it is A) I need the money, however little... B)I get to converse with brass, woodwind and percussion people, of which I interact with little outside of rehearsal. Also, if I didn't do it, I don't know who would -- I can't even get an assistant.
Jam it back in, in the dark.
