Adolescence
I became pretty quiet. I did not talk to anyone about anything I was feeling. At least not until high school, when this INTJ friend moved into my town. She is the first person I ever felt like could understand me, and the first person I ever trusted to share my crazy ideas and feelings with. I did not realize that such human connections were possible before that point. I did not feel that way with my parents or any of my siblings (I have 5) or other friends or classmates or any other adults. It was surprising and a little bit bewildering to me, and I learned a lot through that friendship.
Throughout middle school academically I found all the memorization to be so tedious. I would understand a concept and then be so tired of it by the time the quiz or test arrived and I would space out a lot or forget about assignments or get really frustrated with my teachers or with school in general. Like they weren't focusing on WHAT WAS IMPORTANT i.e. the idea that surrounded all the little facts or procedures. That is probably the time I was LEAST in touch with Se (probably makes sense... adolescence = physically awkward for most people).
By the time I got to high school I had come to accept that, yes, people had opinions of me but that I wanted to care more about my own opinion of myself and my own vision of the world. I was bright, personable, spontaneous, spunky, athletic, a little bit of a nerd, but got along with most people pretty easily. People liked me because I was a free spirit. I yearned for my little high school community to not be so concerned with roles/fitting in, and tried to disrupt the routine in small, beautiful, delightful ways. I just wanted everybody to share in joy and spontaneity. I was generally well-liked but still felt like I did not fit in. I am not sure I would have thought I had any weaknesses at that point in my life. Probably I would have thought the weaknesses were with other people, or problems with "the system." No... I guess I began to realize on some level that details and precision were important, and would get a little frustrated with myself, but mostly still with the system. I also definitely began to take issue with the way that a lot of people in my religion framed things, like they were focusing too much on "the rules" and not enough on "the greatest commandment" (i.e. love). I also became fascinated with symbolic meaning to refer to spiritual/emotional concepts.
Another moment of transformation came at 16 or 17, when I realized that I could see things from another person's perspective, realized that you could take on a different perspective temporarily, see things through another lens. It sort of blew my mind. When I entered high school, I also joined sports teams - I had regained control of motor skills... ha ha ha. So after a couple years of team sports, at the same time as developing the ability to shift perspectives, my understanding of sports (field hockey and other field games) suddenly deepened. I was able to play in a much more... intelligent way. I began to be able to understood the field as a system and ways that I could interact with the system to bring about a desired result. Not necessarily on a conscious level, but on an instinctual level. It certainly felt like a tremendous cognitive shift.
