When I write characters in a fantasy world, I have a hard time coming up with occupations. Seems like mostly everyone in the ancient world was a solder, farmer, fishermen, carpenter, hunter, etc. So I have all these characters, and I need them to have jobs. It's hard to come up with interesting stuff. Also, even harder to create quirks and vices for such characters. The only things they had back then were sex and booze. Is there an exercise (like free association) or something I can do to come up with ideas? I want these characters to stand out and not be cookie cutter. The closest world I can think of to mine is the one in Nausicaa: Valley of the Wind.
