Haven't had one of these for awhile. This thread is for questions or comments that you've felt silly about not knowing/understanding. Let's try to exchange info that seems obvious, knowing that due to the illusion of transparency it really isn't so obvious!
I know a lot of LW-ish people in the Bay Area and I see them explicitly thinking carefully about a lot of big life changes (e.g. moving, relationships, jobs, what habits to have) in just the way you recommended. I don't know if it has something to do with utilitarianism or not.
I'm personally more inclined to think in that way than I was a few years ago, and I think it's mostly because of the social effects of from hanging out with & looking up to a bunch of other people who do so.
