I don't think I really procrastinated as a child. As an adult I think my natural pace is more driven and focused than leisurely.I also procrastinated and even today would prefer to work, walk, breathe, and live at a much more leisurely pace than I am often required to.
The INJ child seems much more focused and self-confident than I believe I was. I do not believe I was a focused or driven child at all. I believe I was exceptionally compliant and my internal world was the occupation of my attention in a floaty, unconcerned about my external environment sort of way. I interacted with the external world in a mostly silent yet intensely observant sort of way.
I have very little memory as a child of interaction with other people that was not incidental. Meaning, I didn't seek out connection with other people really I don't think. Not even to ask "why?". I wondered and was curious about many things as a child, but I pondered them internally and have no recollection of seeking information outside of myself other than through the exploration of fictional worlds in books or television/movies.
I was a personally disheveled child and my physical belongings and space were always in a state of chaos, which I was mostly unaware of unless other people drew my attention and sense of shame toward them. I was neither a good nor a bad student and I don't recall being particularly concerned about education at all as a child other than where my observations might have led me to quiet pondering.
In that recollection of how I was as I child, I really don't see myself clearly in any of the childhood descriptions. I am most closely represented by IFP, I think, though I doubt my childhood experience would really resonate with the childhoods of other IxFP's. I don't know though.
