If a crowded cocktail party feels like a holding cell to you, even as you gamely keep up your end of the chatter, chances are you're an introvert. Introverts are drained by social encounters and energized by solitary, often creative pursuits. Their disposition is frequently misconstrued as shyness, social phobia or even avoidant personality disorder, but many introverts socialize easily; they just strongly prefer not to. In fact, the self-styled introvert can be more empathic and interpersonally connected than his or her outgoing counterparts. The line between introversion and lonely loners gets blurry, however, as some introverts do wish they could break out of their shell.
