I've tested INFJ for quite some time now...though my introversion has always been very weak, I've never really questioned the results, because introverted intuition makes so much sense to me, and much of the INFJ description resounds. In person, I usually have an uncanny handle on the emotions of others, even when it's not obvious to everyone else, and my inner life is very rich.
However, I also acknowledge that being drained constantly by parenting probably skews both myself and my self perception. In the past few months (now that I'm getting more sleep, and operating more like my pre-children self I've had quite a few people call me things like: outgoing, persuasive, charismatic, very confident, charming. Someone actually told me I'd missed my calling as a saleswoman, and meant it as a compliment.
I realize that INFJs can definitely have those qualities, but in conjunction with having my supposed introversion questioned repeatedly, too, I read up more on ENFJs. A lot of it makes sense.
I can strongly relate to seeing patterns in life and relationships, and being something of a mystic, emotionally. I can also be pretty (judiciously) outspoken, and feel literally propelled to make peace in a room and put others at ease...and generally am really relationally adept and silver tongued while doing it. And walk away feeling fairly buzzed from what I'd consider a successful (my goals wise) conversation.
I realize I'm more than a group of letters. However, I'd love to be humored by your thoughts!
