Come up with a crazy business idea.
Truth they say is stranger than fiction. Women sell their used underwear and jars of their farts. Those are crazy but sustainable business models. Most of the things I have sold or tried to sell are in a very sane category. From used books to commercial art there are traditional markets for those. I wanted to hunt ginseng for a while. There are rules and regulations for that and established vendors and processors. I can’t think of anything “crazy” that anyone would actually buy from me.
