" Hedonic adaptation has the power to extinguish our enjoyment of the world. Because of adaptation, we take our life and what we have for granted rather than delighting in them. Negative visualization, though, is a powerful antidote to hedonic adaptation. By consciously thinking about the loss of what we have, we can regain our appreciation of it, and with this regained appreciation we can revitalize our capacity for joy. "

― William B. Irvine , A Guide to the Good Life: The Ancient Art of Stoic Joy
