1. An exaggerated sense of self-importance (e.g., exaggerates achievements and talents, expects to be recognized as superior without commensurate achievements)
Translation: Grandiosity is the hallmark of narcissism. So what is grandiose?
The simplest everyday way that narcissists show their exaggerated sense of self-importance is by talking about family, work, life in general as if there is nobody else in the picture. Whatever they may be doing, in their own view, they are the star, and they give the impression that they are bearing heroic responsibility for their family or company, that they have to take care of everything because their spouses or co-workers are undependable, uncooperative, or otherwise unfit. They ignore or denigrate the abilities and contributions of others and complain that they receive no help at all; they may inspire your sympathy or admiration for their stoicism in the face of hardship or unstinting self-sacrifice for the good of (undeserving) others. Another example is claiming unusual benefits or spectacular results from ordinary effort and investment, giving the impression that somehow the narcissist's time and money are worth more than other people's.
In popular usage, the terms narcissism and narcissistic, denote absurd vanity and are applied to people whose ambitions and aspirations are much grander than their evident talents. Sometimes these terms are applied to people who are simply full of themselves -- even when their real achievements are spectacular. Common conspicuous grandiose behaviors include expecting special treatment or admiration on the basis of claiming (a) to know important, powerful or famous people or (b) to be extraordinarily intelligent or talented. The grandiose claims of narcissists are superficially plausible fabrications, readily punctured by a little critical consideration. The test is performance: do they deliver the goods?
2. Preoccupation with fantasies of unlimited success, power, brilliance, beauty, or ideal love
Translation: Narcissists cultivate solipsistic or "autistic" fantasies, which is to say that they live in their own little worlds (and react with affront when reality dares to intrude).
3. Believes he is "special" and can only be understood by, or should associate with, other special or high-status people (or institutions)
Translation: Narcissists think that everyone who is not special and superior is worthless. By definition, normal, ordinary, and average aren't special and superior, and so, to narcissists, they are worthless.
4. Requires excessive admiration
Translation: Excessive in two ways: they want praise, compliments, deference, and expressions of envy all the time, and they want to be told that everything they do is better than what others can do. Sincerity is not an issue here; all that matter are frequency and volume.
5. Has a sense of entitlement
Translation: They expect automatic compliance with their wishes or especially favorable treatment, such as thinking that they should always be able to go first and that other people should stop whatever they're doing to do what the narcissists want, and may react with hurt or rage when these expectations are frustrated.
6. Selfishly takes advantage of others to achieve his own ends
Translation: Narcissists use other people to get what they want without caring about the cost to the other people.
7. Lacks empathy
Translation: They are unwilling to recognize or sympathize with other people's feelings and needs. They "tune out" when other people want to talk about their own problems.
In clinical terms, empathy is the ability to recognize and interpret other people's emotions. Lack of empathy may take two different directions: (a) accurate interpretation of others' emotions with no concern for others' distress, which is characteristic of psychopaths; and (b) the inability to recognize and accurately interpret other people's emotions, which is the NPD style. People with personality disorders don't have the normal body-ego identification and regard their bodies only instrumentally, i.e., as tools to use to get what they want.
8. Is often envious of others or believes that others are envious of him
Translation: No translation needed.
9. Shows arrogant, haughty, patronizing, or contemptuous behaviors or attitudes
Translation: They treat other people like dirt.
