I'm not an expert on psychological motivations, so I can't speak to the feelings or motivations of others, just myself.

Most of the time these results are things I find during introspection after social events are over. I can spend 4 hours in a social situation and be one of the drivers that keeps things going. It's later, when I'm alone and meditating, that I discover just how exhausted I was.

My wife is an introvert and is highly skilled at chit chat. She can work a room better than anyone but the most gregarious salesman types. She will remember the names of people that she met 10 years ago, details about their careers, their children's names and what their children studied in college. Doesn't matter if it's a professional event, a wedding, or a funeral, she is always on her game. BUT, she always goes home exhausted.

Have you ever wondered if deep inside you are an introvert that just got very good at pretending to be an extrovert at early age due to social pressure? Western society rewards extroverts.

Are you sure about that? I get the impression that the English culture regards extroverts as freaks of nature and terrifying monsters.
