The selection effect - and why people who move to California from the midwest tend to be unhappy.

The basic idea: those who "think" their unhappiness will be solved by moving anywhere (in this case California) are bound to be disappointed, but those who end up moving somewhere with lower expectations tend to be surprised at how much they like it.  Again, it goes back to lowering expectations.

I have a little personal history with this - I moved across LA from Silver Lake to Santa Monica a couple years ago because I got a new job and could not bear the commute.  I thought I wasn't going to like Santa Monica as much, but it turns out I liked it quite a bit.
