Do you guys think that we are born introverted/extroverted? Or is it more the process of our lives "nature and nurture" that defines which type we are? What if you grew up differently? Would you still be one or the other? I don't remember being so introverted when I was a kid. I personally think that we are all born extroverted and learn to be introverted as we grow. So if it is learned, couldn't it be unlearned?
