"Self-esteem, sometimes referred to as self-worth or self-respect, is an important part of success. Too little self-esteem can leave people feeling defeated or depressed. It can also lead people to make bad choices, fall into destructive relationships, or fail to live up to their full potential. Too much self-esteem, however, as exhibited in narcissistic personality disorder, can certainly be irritating to others and can even damage personal relationships". (Kendra Cherry)
