Only 2 to 3 percent of all inventors make any money from their inventions Oh how true. How true. I invented ToDoCal, the large format todo list / calender hybrid. My customers loved it. It sold like crap. I could never sell more than 300 a year. It was on blogs, amazon, ebay, etsy, my own store. It would not sell more than 300 units a year. Loving a product and wanting a product are 2 different things.
