Not trying to put anyone down but do you see some of these traits among ourselves and that some people have them more than others?
Symptoms of this disorder, as defined by the DSM-IV-TR include:
Reacting to criticism with anger, shame, or humiliation
Taking advantage of others to reach own goals
Exaggerating own importance, achievements, and talents
Imagining unrealistic fantasies of success, beauty, power, intelligence, or romance
Requiring constant attention and positive reinforcement from others
Becoming jealous easily
Lacking empathy and disregarding the feelings of others
Being obsessed with self
Pursuing mainly selfish goals
Trouble keeping healthy relationships
Becoming easily hurt and rejected
Setting goals that are unrealistic
Wanting "the best" of everything
In addition to these symptoms, the person may also display dominance, arrogance, show superiority, and seek power. The symptoms of narcissistic personality disorder can be similar to the traits of individuals with strong self-esteem and confidence; differentiation occurs when the underlying psychological structures of these traits are considered pathological. Narcissists have such an elevated sense of self-worth that they value themselves as inherently better than others. However, they have a fragile self-esteem and cannot handle criticism, and will often try to compensate for this inner fragility by belittling or disparaging others in an attempt to validate their own self-worth. It is this sadistic tendency that is characteristic of narcissism as opposed to other psychological conditions affecting level of self-worth.
