Tracy, that rings a few bells with me, but on balance I'm probably less driven than you - might be a cultural difference, although I'm from the source of Calvinism (maybe that's why!).

A useful measure of the healthiness of one's attitude to work, for me, is what a person says they would do in response to instantaneous financial security - say, winning the lottery. If they say they would still keep working, they have a problem, or at least a limited imagination. (btw, in a meritocracy how can lotteries be justified? - ultimate in unearned income).

What would you guys do? Me - I'd travel, indulge my hobbies, get fitter & healthier, read a lot, see more of my folks. Work would be a distant memory.
