This is one of my favourite subjects, the way in the west we classify people as introverted or extroverted. Sure, there's lots of studies that prove you're either one or the other, so why do I feel like both? First and foremost i'm an introvert, but as a performer, i'm able to safely show my extrovert side. I'm pretty clear that I wouldn't be able to be so creative if I wasn't an introvert and started from introspection. In the west, we think being an extrovert is the right way to behave and introverted behaviour is wrong. We don't understand or accept shyness. We think it's a social mishap. I don't know if my introverted behaviour is learnt behaviour or not, but it is me.
You are right. I didn't consider that maybe I had the extroverted side in me all along, I just couldn't find a way to show it. But then, what other "latent" personality traits might be hidden inside of me? I guess we are all actors to a certain degree and we won't find out what we can do until the right opportunity comes.
