perfectionism.

Perfectionism, in psychology, is a personality trait characterized by a person's striving for flawlessness and setting excessively high performance standards, accompanied by overly critical self-evaluations and concerns regarding others' evaluations.[1][2] It is best conceptualized as a multidimensional characteristic, as psychologists agree that there are many positive and negative aspects.[3] In its maladaptive form, perfectionism drives people to attempt to achieve an unattainable ideal, and their adaptive perfectionism can sometimes motivate them to reach their goals. In the end, they derive pleasure from doing so. When perfectionists do not reach their goals, they often fall into depression.
