Personality can be defined as how one is perceived by others based on their nature, appearance, communication style, and behavior. There are three main personality types: introverts, extroverts, and ambiverts. Introverts prefer solitary activities and feel drained in large groups, while extroverts enjoy social interaction and gain energy from other people. Ambiverts exhibit traits of both introverts and extroverts depending on the situation. Introverts tend to be thoughtful, independent, and prefer a small circle of close friends, whereas extroverts are sociable, outgoing, and energized by others.
