I've been wondering if perhaps the reason many within the INFP or similar types tend to be unhappy, has to do with the way certain societies place so much value on being extroverted, warm, and "normal." For example, I'm often told that I look angry or unhappy because I don't smile often...but it doesn't make sense to me to smile when I have nothing to smile about. Am I supposed to walk around with a fake smile plastered across my face all the time, like a creepy lunatic? I think it's particularly challenging for women, since our level attractiveness can often depend on our ability to be perceived as "sweet" and "friendly." I've been told on more than one occasion that I come off as a "bitch," even when I think I'm behaving completely normal. I'm sure INFP men are often told they seem cold or indifferent, since they're less likely to be the dude in the middle of a room commanding every second of attention.
