I live in a dormitory while I study a trade. I recently put up a notice offering standard repair services, such as assembling furniture, putting up lamps and whatnot.

My only customers so far have been women with hopelessly easy jobs. This morning I charged $10 to put a chain on a bike for a girl, took me literally 5 minutes. In the meantime, she was observing me with a sly smile.

It's good spare cash, and it helps me practice general skills, but the sheer satisfaction of proving to myself how invaluable men really are to women, and how much we can capitalize on it, is the true reward.
