But you surely can't suggest that this property of you should generalize to other people? Yes, there is a component of happiness related to feeling productive, but surely it's not 100%, and it varies from person to person. Your advice effectively says to ignore your non-work life goals that cost money because only your work-goals-productivity will make you happy. I doubt this very much, and certainly know that it's not true for anyone I've ever worked with.
