This doesn't really fit me. I did have a vivid imagination and was off in my own world, but most of the rest don't fit. I didn't necessarily prefer one on one interaction to large groups back then; I probably preferred large groups actually. I didn't like art, music, or books at all. I never listened to music, never read unless forced to, and would have preferred if art class didn't exist. I didn't hang back in social situations either, I jumped in. I wasn't private, though the substance of what I had to share wasn't that deep (guess what I think about pok'emon!). Unplanned events didn't bother me; I think I thrived on them. I was always ready, 24/7 (always hyper too, you might say I was chaos). I definitely preferred team sports like soccer and basketball, and I thrived on and excelled at physical activity- I think my ES is very well developed for an INFJ. I wasn't a perfectionist at all- I didn't care how I did. I wasn't serious or intense unless I was under pressure. I definitely didn't seem older than I was, just about all of my friends were my age too. I wasn't original or really independent (sometimes I was overly dependent when I didn't need to be), and I only valued my "uniqueness" because it helped me fit in with others (they decided how I was "unique" too basically). Its true I wasn't concerned about grades, until I got hell for them, but I didn't ever want to completely understand something that interested me, unless you count pok'emon.
I don't believe that children really fit into MBTI. Its even hard to put 16 year olds into it. As a child, my Se and Fe were pretty much all I used until I was put under pressure, and around the age of 10-11 my Ni showed up and my Ti started working in full force and continued to develop from there as my life began to suck more and more and I became extremely introverted, depressed, etc....
