Probably INFJ. Other people tend to insist on that type for me more than I do. I was more organized and driven when younger, so I think they would typically say J. It's funny because I am organized, structured, acting, upon ideas and concrete objects, but when it comes to people I'm the opposite. I can organize events, can enjoy reasoned debates, and I keep my stuff organized because i could never find anything otherwise, and it makes me feel anxious to have random piles of stuff around.
My social interface is less J than it is for most Ps (if that makes sense). I think that's what Ni does to Fe for some people. Last week a young teenage student declared in a lesson, "you're not a teacher! I was talking the whole time you were and you didn't tell me to stop." It made me feel a bit discouraged, but I know she didn't mean anything by it. She kinda blabs with a limited amount of control over it, and she's cute, smart, I like her, so I just ignore what comes into conflict with what I'm trying to do - hence the conversation problems. I lack the ability to force people to do anything - even within the normal range of what I'm supposed to push. My INFJ brother is the same way, and my Fi-dom mother and sister to a point, but my sister can feel more directive in a way. She is still extremely Fi-dom P, though.
