How important is it to you during your free time that things be organized and structured?
I like things to be organized, but to certain extent. My room and my locker are both terrible messes, but they make sense to me, so I can easily find what I need and put it back where I can find the next time I need it.
In regards to free time, I don't follow any set plan. But everything else in my life is practically set in stone. I plan which textbooks I take to which classes (I bring geometry stuff to chemistry, my locker is too far away from both classes). I'm also extremely punctual, and get to things early. I also plan most of the events in my life, and hate doing things last minute because somebody else didn't do something early enough.
I guess for me, free time is a time to wind down and just do whatever I happen to want to do, whether it be reading, watching TV, researching topics online, or just thinking. However, I can't truly relax knowing I have an impending due date and I know I haven't done enough work, or knowing that my plans have gaping holes and inconsistencies.
The big reasons why I thought I was an INTP were my love of theory and knowledge, a strong dislike of people who use words incorrectly (why do people call binders notebooks when they're really binders? They even have the proper name written on them!) or fail express their idea correctly,and (sometimes, it depends on the exact circumstances) the feeling that I failed miserably, no matter what people say or do to convince me otherwise.
