Introversion is a personality trait characterized by a focus on internal feelings rather than on external sources of stimulation. Introverts and extroverts are often viewed in terms of two extreme opposites, but the truth is that most people lie somewhere in the middle. But being an introvert does not necessarily mean that you're a shy or socially anxious person. Its just that they probably would prefer being alone by themselves and read a book rather than going to a party
Introverts are also usually good at having thought provoking conversations, being observant, being effective salespeople, listening to other people, being a source of freedom and thinking before acting. Instead some of the great people today themselves are introverts like Mark Zukerberg, Bill Gates, Steve Wozniak, Barack Obama and any more. So if you're an introvert don't feel bad about yourself for not being social and instead focus on the positive aspects.
