I used to be an INFP-- strongly. That's how I was in high school, when I originally took the Myers-Briggs test. And it fit. I had no qualms with seeing myself as an INFP.
One of the things that has changed is that I've become much more outgoing. Talkative. Confident. Certainly not in some situations, but I've jumped yards overall. Thinking I had certainly flipped to an "E," I retook the Myers-Briggs test again last year, and although I was less "introverted" than I had been the first time, it was still largely on the "I" side of things.
Now, I'm on the border of I/E and on P/J. I saw the "E" thing coming. I did NOT see the "J" as being possible at all. I suppose it makes sense though. Perceiving/Judging was once explained to me in flower terms. "A 'P' wants flowers, and wants to buy flowers for their significant other. A 'J' realizes they will die quickly, and would rather show their affection in ways that don't rot" -- I think those were the exact words from Dr. J, the guy who came to talk to us about the Myers-Briggs personality typing back in 11th grade Gifted Studies. He was right. Back then, I liked flowers. Now, flowers are stupid. I wouldn't even want to grow them in my garden, because they aren't useful. I'd rather grow basil.
Currently, with my new borderline letters, I could be considered a:
INFP
INFJ
ENFP
ENFJ
Reading the description of an ENFP makes me lean towards believing that I am that type. Thoughts?
