I may be a genius.
Sometimes I have these brilliant ideas that answer significant problems, only to discover the thing I invented already exists. I wrote a story about mall cops and then two (awful) movies about mall cops came out. I invented a tray that you could strap to yourself so you could walk up and down stairs carrying things and still have free hands, but then I remembered vendors use those trays at every sporting event ever. I also thought of a vending machine that grabs your drink for you so it doesn’t fizz when it falls down. That’s already a thing too, so… I may be an idiot.
