Am I an introvert or an extrovert?

Introverts prefer the company of people they know well and tend to have a smaller, but closer, circle of friends. — Oduaimages

The concepts of introversion and extroversion were first introduced by Carl Gustav Jung, one of the fathers of modern psychology.

Jung defined introversion as an “attitude-type characterised by orientation in life through subjective psychic contents”, and extraversion as “an attitude-type characterised by concentration of interest on the external object”.
