The utilityin you is the ultimate criterion of what's right and wrong, but it's not necessarily the best guide to apply all the time in day to day circumstances. i think we see that in lots of contexts, that we want to get absorbed in activities for their own sake. A simple example would be, if you're playing some sporting event, you don't really want to be thinking about will it maximis utility of my team wins. So i think sometimes you have to put those things aside and think about what you're actually engaged in and get involved in it.
