One central dimension of personality is introversion versus extroversion. An introvert is a person who draws energy from time spent alone. Introverts find social situations draining and need time alone to recharge after being around people. They tend to be introspective and like to explore thoughts and feelings. They may prefer to talk about concepts and ideas rather than making small talk.
Introverts usually like to work behind the scenes, prefer written to verbal communication and express themselves only after careful thought. Introverts make up 25% to 40% of the population. Introversion is not the same as shyness or social anxiety; being an introvert does not mean that you are necessarily shy or socially anxious.
