‘Desire – grasping, clinging, greed, attachment – is a state of mind that defines what we think we need in order to be happy. We project all of our hopes and dreams of fulfillment onto some object of our attention. This may be a certain activity or outcome, a particular thing or person. Deluded by our temporary enchantment, we view the world with tunnel vision. That object, and that alone, will make us happy. Who has not been greatly infatuated with some idea or some person, only to look again two months later, six months later, a year later, and think, “What was that all about?” (Lovingkindness)
I would only add that not only do we all do it, but we all do it all the time.
