Strangely enough, I have noticed that I have exhibited different personalities in different parts of my life.
As a child, I am sure I was ENFP. I was enthusiastic, talkative, jumping from one activity to the next; gushy in my attempts to get attention and positive feedback; unafraid to TOTALLY speak my mind about everything (including screaming to a punk in a department store "WHYYYYYY IS YOUR HAIR GREEN?!?!?!?! To the point where she totally flipped out, turned red, and stormed out of the store); debated about politics even at the age of 8 (my family was politically engaged); totally talking more to my classmates than paying attention in class - usually about fanciful things; pretending to have lots of kids in a class and teaching them things, like how to read; making up weird stories; acting out Star-Wars movies and Rainbow Bright episodes that I made on my own, in addition to pretending to dance like the evil Peculiar Purple Pie Man of Porcupine Peak (Yat-dah-dah-dahdahdah-yat-dahdahdahdah-DAH!) from Strawberry Shortcake (I wonder if they still have those movies); making up my own weird, bizarre stores; going off on tangents; playing by myself for hours on end with my fifty billion made-up friends - well I was so weird that I did not have many REAL friends who could put up with my crazy, abstract, impractical, fanciful notions; HATED sports. My family probably thought I was schizophrenic for the first few years of my life. (j/k)
When I was in high school and college, I tested consistently INTJ, once or twice INTP. My only guess for this strange result was that my tertiary function Te sort of "took over" in an academic environment. In addition, I was so focused on my "work" that I never really concentrated on my social life. So my answers were skewed. Never focused on how I look or appeared. Never went to parties. Straight arrow. Never felt comfortable around other people, primarily because I had nothing to talk about - I was weird, unconventional. Got excellent marks in school (when I liked the teacher). Hated working in groups (those lazy bastids!!!) I was totally arrogant, stubborn, and closed-minded. Elitist, too. Convinced I was right, and everyone else was dead wrong. Did not really care what other people thought about me. Was always the person people came to with problems, though (I guess they felt the hidden NF?!?!) Was the chronic hand-raiser, participator, etc. - but only because I knew it would get me points and good grades. Had goals, and set out to accomplish them at all costs. Total believer in survival of the fittest and might is right philosophy. Good grief, I was a monster!!!
After I moved to Germany, I initially tested INFJ/INFP. I think it was "safe" to let my Fi shine again, I guess. But I still needed to kind of come out of my shell a bit.
After I began teaching and really came into my own, I have consistently tested ENFP. I love working with people - the more I teach, the better I feel; groups are great (I feel almost giddy after eight hours with a group of people); I love socializing with certain groups of people (as long as we have things in common and they do not look at me like I am a crazy idiot); still need my quiet time, though; enthusiastically jump from one hobby to the next (damn it!!!); love to learn - I have an innate curiosity; yes, I just came into my own, I think.
So, yeah, that's my "history." Has anyone else experienced anything similar?
