A novel about a guy his homeless. He's greatest ambition is to collect bollets and cans, he consider himself "self-employed". Let's say his been doing it for ten years. Everyday. His poor, but he only lives at minimum until has alot (really many) bottles/cans. He goes to a store and return them in these bottle/can machines, and earns a fortune. His life takes a turn instead he becomes rich and powerful. Hahah, just an idea. Are there any books like this?
