I don't have much formal education, and I'm currently taking an, uhm, extended break from school (7+ years and counting). So I take whatever jobs come up.
Last was as customer service, and incoming orders, in a call center. Was Ok enough. Some people you laugh with, others you want to murder, slowly, with a rusty spoon. You learn a lot about people...
Next job will probably be at a café where people with various (relatively minor) psychical issues spend some of their day. Some have bigger issues than others, but most of them are people who are well enough to live alone. I worked here before, for a while, and it is an interesting job.
