“Happiness fades by design, precisely because it’s a means to an end, not an end in itself. We continually need to meet our psychological, emotional, and physical needs to remain healthy. If one meal were enough to provide lasting happiness, we would slowly starve to death afterward … Consequently, there’s a limit to our happiness, which is defined by the amount required to satisfy a biological need. Exceed this amount, and the result isn’t more happiness but the discomfort and disease that follow from overindulgence. While some may be good, more isn’t necessarily better, and too much of a good thing can be a bad thing.”
