The apathetic may lack a sense of purpose, worth, or meaning in their life. They may also exhibit insensibility or sluggishness. In positive psychology, apathy is described as a result of the individuals' feeling they do not possess the level of skill required to confront a challenge (i.e. "flow"). It may also be a result of perceiving no challenge at all (e.g. the challenge is irrelevant to them, or conversely, they have learned helplessness). Apathy is something that all people face in some capacity and is a natural response to disappointment, dejection, and stress. As a response, apathy is a way to forget about these negative feelings. This type of common apathy is usually felt only in the short term, but sometimes it becomes a long-term or even lifelong state, often leading to deeper social and psychological issues.
