In psychology, grit is a positive, non-cognitive trait based on a person's perseverance of effort combined with their passion for a particular long-term goal or end state (a powerful motivation to achieve an objective). This perseverance of effort helps people overcome obstacles or challenges to accomplishment and drives people to achieve.
Distinct but commonly associated concepts within the field of psychology include perseverance, hardiness, resilience, ambition, need for achievement, conscientiousness, and tenacity. These constructs can be conceptualized as individual differences related to the accomplishment of work rather than as talent or ability. This distinction was brought into focus in 1907 when William James challenged psychology to further investigate how certain people can access richer trait reservoirs that enable them to accomplish more than the average person.[1] However, the construct of grit dates back at least to Francis Galton,[2] and the ideals of persistence and tenacity have been understood as a virtue at least since Aristotle.[3]
