Confidence in one’s value as a human being is a precious psychological resource and generally a highly positive factor in life; it is correlated with achievement, good relationships, and satisfaction. Possessing little self-regard can lead people to become depressed, to fall short of their potential, or to tolerate abusive relationships and situations.
Too much self-love, on the other hand, results in an off-putting sense of entitlement and an inability to learn from failures. It can also be a sign of clinical narcissism, in which individuals may behave in a self-centered, arrogant, and manipulative manner. Perhaps no other self-help topic has spawned so much advice and so many (often conflicting) theories.
