Steven Johnson talks about moving from New York to San Francisco:
But the other reason for the move, in truth, is that I’ve come to think that this kind of change is intrinsically good in itself, wherever you happen to move. An old friend who did a similar westward migration a few years ago told me that the great thing about moving is that the changed context helps you understand yourself and your family more deeply: you get to see all the things that you really loved about your old home–and the things that always bothered you without you fully recognizing it. Like a good control study in a science experiment, the contrast allows you to see what really matters. Changing the background scenery helps you see the foreground more clearly.
