"We construct our idealized world, in fantasy, according to all the information we have at our disposal. We use what we know to build an image of what we could have and, therefore, of what we should do. But we compare our interpretation of the world as it unfolds in the present to the desired world, in imagination, not to mere expectation; we compare what we have (in interpretation) to what we want, rather than to what we merely think will be. Our goal setting, and consequent striving, is motivated: we chase what we desire, in our constant attempts to optimize our affective states. (Of course, we use our behavior to ensure that our dreams come true; that is healthy “adaptation.” But we still compare what is happening to what we want—to what we desire to be—not merely to what we cold-bloodedly expect.)"
