Perfectionism, in psychology, is a belief that perfection should be strived for. In its pathological form, it is an unhealthy belief that anything less than perfect is unacceptable. Perfectionism can drive people to accomplishments and provide the motivation to persevere in the face of discouragement and obstacles. Adaptive perfectionists have lower levels of procrastination than non-perfectionists. High-achieving athletes, scientists, and artists often show signs of perfectionism. For example, Michelangelo's perfectionism may have spurred him to create masterpieces such as David and the Sistine Chapel. Perfectionism is associated with giftedness in children.
