One cannot divine nor forecast the conditions that will make happiness; one only stumbles upon them by chance, in a lucky hour, at the world's end somewhere.
DANIEL GILBERT, Stumbling on Happiness
We all have direct experience with things that do or don't make us happy, we all have friends, therapists, cabdrivers, and talk-show hosts who tell us about things that will or won't make us happy, and yet, despite all this practice and all this coaching, our search for happiness often culminates in a stinky mess. We expect the next car, the next house, or the next promotion to make us happy even though the last ones didn't and even though others keep telling us that the next ones won't.
