By synthesizing research from psychology, economics, and philosophy, Propelled criticizes notions of well-being that overly focus on positive emotions and experiences. Against a tradition that has condemned boredom and frustration to be emotional obstacles that hinder human flourishing, Propelled shows that to live a good life we must experience and react appropriately to both. In addition, it argues that we need to anticipate, wait for, and even long for future events. Boredom, frustration, and anticipation are not unpleasant accidents of our lives. Rather, they are vital psychological states that illuminate our desires and expectations, inform us of when we find ourselves stuck in unpleasant and unfulfilling situations, and motivate us to furnish our lives with meaning, interest, and value.
