I'm a freelance writer, the bulk of which is spent writing for news outlets (or pseudo-news... the few months I spent working for the Onion were fantastic), though I do a great deal of blogs, ghost-writing, and advertising, too. I also write as a hobby, and every once in a while I get the chance to sell some of my own stories, too.
This is supplemented by a lot of entry-level customer service type things from time to time, like the cashiering I'm doing for a grocery store right now.
