I've come up with new prompts for them because they're so inspiring. In general, people have a better time starting a writing project if they start with a list. All writers use lists because they are so much easier to generate than paragraphs of perfect sentences.
This past week I asked them to make a list of every job they've ever had. They had no need to limit themselves to paid work. They should list every job they had in the family, every formal role they played at home as well. Once they'd made a list, I asked them to focus on one job, perhaps a favorite job or least favorite, and describe it in more detail. Then I asked them to describe a memorable co-worker. Finally, I asked them to offer written advice to anyone entering the workforce now. Our participants love giving advice, and they're pretty good at it, too.
Well, the stories came pouring out of them. One man described his jobs shining shoes and selling magazines as a very little boy and how he was expected to strip off his clothes when he came home to prove he wasn't hiding money from his parents. Another woman wrote about her first after school job, which was helping an elderly shut in bake cakes and pastries to sell. She remembers what she baked, how much money she made and what she bought with it.
Try it. It works.
