An introvert is likely to enjoy time spent alone and find less reward in time spent with large groups of people. They prefer to concentrate on a single activity at a time and like to observe situations before they participate. They are more analytical before speaking.

Excerpt: Introverts are more concerned with the inner world of the mind. They enjoy thinking, exploring their thoughts and feelings. They often avoid social situations because being around people drains their energy. This is true even if they have good social skills. After being with people for any length of time, such as at a party, they need time alone to “recharge.” When introverts want to be alone, it is not, by itself, a sign of depression. It means that they either need to regain their energy from being around people or that they simply want the time to be with their own thoughts. Being with people, even people they like and are comfortable with, can prevent them from their desire to be quietly introspective.
