“I don’t even see how people who do have a regular real time job can even do this “on the side”.”
I have three regulars. One does well as a stylist, one is in grad school, and the other works in hospitality. I get along with all three so well that I see them regularly on the side. None have ads anymore. It is possible to have a full-time gig and do this on the side if you have a small group of regulars. In fact, it’s a great way to supplement income and have some nice trips as well.
