Narcissism

An excessive preoccupation with the self — popularly used as shorthand for vanity or self-absorption, and clinically codified as Narcissistic Personality Disorder, characterised by grandiosity, a need for admiration, and a lack of empathy. The term shades into ordinary self-consciousness at one end and into manipulative or pathological behaviour at the other. A recurring concern in David Foster Wallace's work, where it is repeatedly diagnosed as the hidden flip side of self-loathing, depression, and the recursive trap of being unable to stop thinking about how you are perceived.
