Extroverts are perceived to be the types of people who enjoy human interactions such as social gatherings, parties, public speaking, and other activities associated with being around people. They tend to feel bored and lonely by themselves and feel energized when around other people. Introverts, on the other hand, are perceived to be the types of people who enjoy spending time alone reflecting on their own mental selves. These types of people tend to be easily overwhelmed by too much energy from the external environment.
