Why do extroverts like action, and introverts like calm?
It has to do with two powerful chemicals — dopamine and acetylcholine, “jolt juices” that hugely impact our behavior, according to J. Allan Hobson, a professor of psychiatry at Harvard.
Dopamine gives immediate, intense zaps of happiness when its users act quickly, take risks, and seek novelty.

You’re not imagining it. That extrovert who seems so different from you? It’s because his brain is different.
So it ultimately boils down to sensitivity to Dopamine! Well if science says this is so then I guess this is it! I wonder, however if Dopamine Sensitivity can be controlled through medicines, then it goes without saying that one can transform and introvert into an extrovert and vice versa? Well, would one really want to change one's prediliction towards Extrovertism or Introvertism? It is a misnomer however to label any of these tendencies wrong or unacceptable because they both belong to different but necessary characteristics of behaviour!
