The pleasure of getting what you want is often fleeting. You dream about getting a promotion, being accepted into a prestigious school, or finishing a big project. You work every waking hour, perhaps imagining how happy you’d be if you could just achieve that goal. Then you succeed, and if you’re lucky you get an hour, maybe a day, of euphoria, particularly if your success was unexpected and there was a moment in which it was revealed (… the envelope, please). More typically, however, you don’t get any euphoria.
