Self-acceptance is acceptance of self.
According to Shepard (1979), self-acceptance is an individual's satisfaction or happiness with oneself, and is thought to be necessary for good mental health. Self-acceptance involves self-understanding, a realistic, albeit subjective, awareness of one's strengths and weaknesses. It results in an individual's feeling about oneself, that they are of "unique worth".
In clinical psychology and positive psychology, self-acceptance is considered the prerequisite for change to occur. It can be achieved by stopping criticizing and solving the defects of one's self, and then accepting them to be existing within one's self. That is, tolerating oneself to be imperfect in some parts.
Some distinguish between conditional and unconditional self-acceptance.
