Richard Moorhead makes an excellent point about the need to consider the things other than monetary compensation that make work rewarding or unrewarding. I always think that money isn't about money. It's about self-esteem. Our culture is depressingly focussed on the idea that lots of money = happiness. There's various research that suggests lottery winners may revert to their pre-win happiness level (see http://theconversation.com/couple-wins-the-lottery-twice-but-will-it-make-them-happy-39717). Maybe it's time to recognise that there's more to happiness than earning (or winning!) bucket loads of money.
