When I was about 8 I managed to sell pieces of a bamboo stick I cut up... I can't remember where I got it from, nor what the kids I sold it to were supposed to do with it...
A few years later I started a money lending service, but being a skinny 11 year old kid at the bottom of the food chain (first year in secondary school) I had a fair few people default, and what was I going to do about it? I don't think I charged interest either, I hadn't learned what that was.
