Are you an extrovert or an introvert?

I am an introvert, because I am a quiet and less sociable person. I prefer to have less people around me because big crowds make me uncomfortable. I regain my energy most the time when i'm with some people but not a lot of people. I think that introverts have it easier because extroverts are more likely to have a lot of drama. I think that if the world would be more open to the public because there wouldn't be any shy people and there would me more success in businesses because there would be more team work  if everybody was an extrovert. If everybody was an introvert then the world would be all independent and things would be hard to do because team work helps a lot.
