Making money from an idea is always very satisfying, I had my first paper route at 11, but I was never focused enough to appreciate the money it brought me. I spent as I got it and can't recall on what, probably candy. Cash slipped through my hands like sand so I always stayed employed. The lesson I got is "I can always get a job." It's mostly through good fortune (and never having college debt) that I have 'enough' money today, because I learned in my fifties, I can always get a job--one that pays crap!
