In your opinion ,what is the optimum weekly work hours? I think around 50 is good.On Sunday, I can really relax fully if I think of nothing else. 60 is really pushing it though. However, I've seen a few sites were it is said that productivity actually increased if the work week was restricted to 40 hours. The work cited (and I haven't looked at it in details) include some done at Ford and various places in academia. Legit? It is certainly extremly counter-intuitive, and I'm still not sure I accept the premise. This stems more from my experience in school, but I have seen that people who studied hard beyond 40 hours generally speaking had better grades then those who didn't (I wasn't part of that group). Also, I can't think of many entrepreneurs who have not spent long hours at work.
