I don't think I really have deadlines for long-term goals. Maybe that comes down on the P-side.
A couple things I kind of want to throw out there: I feel like I'm comfortable (and often have to) be spontaneous with things that I'm in control of... as in, if I'm making a presentation or, as I mentioned, writing a paper, I almost have to do it with minimal notes or outlines or rehearsal; I actually come off as a lot more natural and organized when I wing things like that. When it comes to things like that, I'm very quick on my feet. Is this P-heavy?
As a "both", I seem physically disorganized to people: I can have a messy workspace, but at the same time it makes sense to me, and if I need to find something I will usually know where in the madness that something is when I need it... if that makes any sense.
Finally, the case for "J": when it comes to things that involve circumstances out of my control, I do get much more uncomfortable not having a plan. If I'm going to go somewhere, I need to have some idea of specifically what's going to happen, how long I can expect to be gone, etc. Even when planning outings/day trips with friends, I'm usually the one fighting to set a specific time and meeting place, say, whereas other people want to just have much more lax plans and figure it out as we go along. I also find myself having to organize practical things like that within a group: carpools, some kind of timetable, calling everyone to make sure they're up to speed and reminding them what they need to bring, etc. I feel that oftentimes if I don't do this, things will get screwed up and we'll lose time or, worse, miss whatever we're planning to do. (E.g., if we're going to see a movie, I'm not comfortable showing up at the theatre two minutes before it's scheduled to start).
I hope this is making sense. To reiterate but rephrase: I almost feel like I'm P with myself but J with other people? I tend to enforce a lot of the J stuff less if I'm doing something myself, and maybe this stems from a general distrust, who knows.
