And because I've already suggested that elements of the various personality disorders often combine, here are a few of the features of Paranoid Personality Disorder that may be of interest: suspicion that others are harming or deceiving him or her, reading hidden demeaning or threatening meanings into benign remarks or events, persistently bearing grudges (unforgiving of perceived injuries), quick to counterattack to perceived attacks on his or her character. To qualify for any of the personality disorder diagnoses, the individual must either be distressed by these characteristics or, in some way, dysfunctional. Very successful people can be dysfunctional in many aspects of their lives.
