"If you are on the other end of the self-esteem spectrum and tend to see yourself as undeserving and unworthy, you will rewrite nebulous behavior as the result of attitudes consistent with the persona of an incompetent person, deviant, or whatever flavor of loser you believe yourself to be. Successes will make you uncomfortable so you will dismiss them as flukes. If people are nice to you, you will assume they have ulterior motives or are mistaken. Whether you love or hate your persona, you protect the self with which you’ve become comfortable. When you observe your own behavior, or feel the gaze of an outsider, you manipulate the facts so they match your expectations."
