Mine goes the other way. I have been nothing but a photographer my whole life 24-61. Last year I decided to do something (anything) different part time. I took a job selling artisan meat products in local farmer's markets on the weekends. It is unlike anything I have ever done before and causes me (normally a recluse and darkroom rat) to stand in crowded markets and talk all day to people about the meat product. All the people who know me in the markets consider me the "Salami guy". Most people assume I own the meat company since I am an old man selling in the market. No one at all suspects that most my time is spent thinking about visual art.
The other day I asked the goofy lady who sells balloons at the markets if she does anything else in life. Yes... she is a photographer and a documentary film maker. Never would have thought it.
