Though introverts are drained by interaction, we can take immense pleasure in watching the scene around us.

Extroverts are more attuned to social rewards, so they are more likely to flash a smile for effect. A notable exception are introverts - like me - whom I call "socially accessible" introverts. We have been trained well to smile and nod, which can place a burden on our processing efforts.

An introvert may feel asocial when pressured to go to a party that doesn't interest her. But for her, the event does not promise meaningful interaction. In fact, she knows that the party will leave her feeling more alone and alienated.

America is a noisy culture, unlike, say, Finland, which values silence. Individualism, dominant in the U.S. and Germany, promotes the direct, fast-paced style of communication associated with extraversion. Collectivistic societies, such as those in East Asia, value privacy and restraint, qualities more characteristic of introverts.

Your nature is not the problem. The problem is that you have become alienated from your nature -- from your power source.

When a quiet introvert talks, heads turn, and that's power.

Introverts keep their best stuff inside—that is, until it is ready. And this drives extroverts crazy! The explanation for the introvert’s behavior—and there must be an explanation for this behavior, say the extroverts—is that he or she is antisocial, out of touch, or simply a snob.
