Varieties
Extroversion
Extroversion is "the act, state, or habit of being predominantly concerned with and obtaining gratification from what is outside the self".[7] Extroverts tend to enjoy human interactions and to be enthusiastic, talkative, assertive, and gregarious. They take pleasure in activities that involve large social gatherings, such as parties, community activities, public demonstrations, and business or political groups. Politics, teaching, sales, managing, and brokering are fields that favor extroversion. An extroverted person is likely to enjoy time spent with people and find less reward in time spent alone. They tend to be energized when around other people, and they are more prone to boredom when they are by themselves.
Introversion
Introversion is "the state of or tendency toward being wholly or predominantly concerned with and interested in one's own mental life".[7] Introverts tend to be more reserved and less assertive in social situations. They often take pleasure in solitary activities such as reading, writing, drawing, and using computers. The archetypal artist, writer, sculptor, composer, and inventor are all highly introverted. An introvert is likely to enjoy time spent alone and find less reward in time spent with large groups of people, though they tend to enjoy interactions with close friends. They prefer to concentrate on a single activity at a time and like to observe situations before they participate.[8] Introverts are easily overwhelmed by too much stimulation from social gatherings and engagement. The introvert tends to thoroughly think before verbalising their thoughts.[9]
Introversion is generally not the same as shyness. Introverts choose solitary over social activities by preference, whereas shy people avoid social encounters out of fear.
