Languishing—the state of mental weariness that erodes our self-esteem, motivation, and sense of meaning—can be easy to brush off as the new normal, especially since indifference is one of its symptoms. It is not a synonym for depression and its attendant state of prolonged sadness. Languishers are more likely to feel out of control of their lives, uncertain about what they want from the future, and paralyzed when faced with decisions. Left unchecked, languishing not only impedes our daily functioning but is a gateway to serious mental illness and early mortality.
