Roni Di Lullo didn't let the fact that dogs look kind of dumb in sunglasses stop her, she pressed on with the making of "Doggles" for motorbiking, boat riding, action doggies, then even made prescription lenses. Her company is worth $3 million.
Scott Stillinger's kids helped him invent something to guide him to riches. They were terrible at catching, so to make it easier he tied some rubber bands around a solid core, cut them up a bit, and the Koosh ball was born. It's not known how much he got for the company, but it sold a few years later for seven hundred million dollars so he's probably doing okay.
Scott Boilen woke up one day and said "What if you could wear a blanket" and now millions of people do. He made the snuggie, and with it a few hundred million dollars to help him buy his own groceries, and probably flip the script and flick a few family members a house deposit himself.
