The Key to Happiness

I called my mother about a half hour a go to complain (in very vague terms, of course) about my weekend from Hell, and right after I said hello she jumped into this following exchange:

Mom: Did you know that Danish people are the happiest people on the planet?
Me: Um, no.
Mom: We're watching a thing on 60 Minutes about it. It's examining why they're so happy.
Me: Well, why are they so happy?
Mom: Because they have low expectations!

I'm not sure if that did anything to cheer me up or not.
