Caine Monroy, a 9-year old boy living in Los Angeles, went with his Dad to work at his used auto parts store in East LA all summer long. He loves games and decided to make an arcade out of cardboard, tape, and brilliant ingenuity. He built a claw machine, a double shot, a soccer scorer, and all sorts of other games you'd find at an arcade - all out of cardboard. He even had a "Fun" pass for $2 which gave you 500 turns instead of 4 for $1. Simply genius.
Once his first customer finally came, he realized the potential and organized a massive flash mob. Once it got to the homepage of Reddit, or as he called it "the frontpage of the internet," success would not be denied. Just watch the video. It's so inspiring. If only we (founders) would all be so persistent.
