Why are we never satisfied.. Well it’s a good thing you’re not, because that’s the way we feel the motivating force behind all development, both in the physical and the spiritual, hidden, causative level of nature. Anything we feel as movement; from moving to some other part of the world, to the most subtle shift of inner attitude happens only because this force has made us so uncomfortable and unable to fulfill our desires in our current state, that we begin to feel a need for a greater satisfaction that we calculate exists in that new situation. We move just that far, and no further. A person doesn’t even move a finger or scratch their nose if not for this calculation: how to get the maximum amount of pleasure for the minimal amount of effort. It’s the E=mc2 of the ego. The formula’s is so pervasive that we never choose anything unless it’s presented to us in this way. We always choose between what we consider painful or pleasurable, and we always choose pleasure.
