(If you thought of it, and you arent’ in the 130+ category, someone thought of it already, and decided it wasn’t possible, or worth it. on the other hand, if you are willing to serve niche customers who you can empathize with that is something you can turn into money. But you must get customers, you cannot attract them.)
