I don't need to see a psychiatrist to cure my introversion. People tend to say to introverts,
"Why don't you talk more? Why are you so quiet?"
and many times, I hear,
"You need to come out of your shell."
I find those remarks rather off-putting and even insulting because it's an indirect way of saying, "your personality sucks and you need to change".
It would be no different than me telling an extrovert "Why don't you shut up? You talk too much." and-
"You need to crawl into a shell".
The fact is, being an introvert isn't a personality flaw for which I need to seek therapy any more than an extrovert needs to seek mental treatment for his or her personality (though sometimes I think some should).
Extroverts talk to think, and introverts think to talk.
I've always been a reflective person and most often through my life, from childhood till now, I've been the quietest one in the room. I tend more to listen to the others in the group and get amused about how so many think their input is more valuable than anyone else's. People often say dumb things, and it makes great material for my cartoons.
A better question might be, are cartoonists great introverts or are introverts great cartoonists?
