I think the real underlying question is about time-money tradeoff. As for a 4-hour work week, there's a sense in which a work week that is too short will bore you to death. I would take a pay cut in exchange for, say, 30 or 20 hour work week, but 4 hours a week seems extreme. Plus, if you are doing something you enjoy, "work week" doesnt have the same meaning as a traditional 9-5 job.
