One more thought about this spouses-who-work-outside-the-home-have-more-stress thing. I think a big part of it for me is the fact that I'm performing on a larger stage at work. My failures and successes, big and small, are seen by many more people, people who don't know me very well, people who don't care about me, people the world considers Very Important, etc. I do wonder whether that's something that translates to other people in my position, because I do have particular sensitivity to that sort of thing--what people think of me. But you don't have to be self-obsessed to care that Corner Office Partner X and Federal Judge Y and Opposing Counsel Z think you're an idiot, right? I suspect not.
