I actually get it, FP's are formidable people, talented with spontaneity. My Judging ability keeps me wanting to organize everything important in my life such as my studies and the way my room looks like :P but i do have a tendency to use the FP conception of "making what i feel like, when i feel like it" for some other things, rather not as important and i know it is a great feeling. The only problem is when making a real important decision FP's tend to freeze because they really dislike pressure and Deadlines.
It is a matter of fact not "the wanting to do so" premise but the "needing to feel free" what keeps them from choosing a preferred side. They just look everywhere for pros and cons in a non-aware state; this making them unbelievable understanding of how people feel and what they could do to help them. This does mean they worry about the future, but they just conceive it in another way, they really enjoy living on the right here right now, because it is easier to make a decision at the time, then compromising for something they might not feel like to do in the future. Being an FP is about living life day by day instead of knowingly planing what when and were to do. Forget about schedules, give an FP a problem to solve where he/she's interested with and they will have it solved in no time ;)

I need the commitment. I used to be all for the spontaneity all the time. Now, I can only handle the spontaneity some of the time. If time is money or time is effort, I need a plan. It doesn't have to be super detailed, but I need one. You can always deviate, but after a while inconsistency will become an annoyance from someone you expect to be reliable.

You know it, Ps are flakes, especially FPs ! :-)

i m an INFx..i agree that when the anxiety-level of a situation dictates, i shift quickly from P to J, even impatiently so. i think thats because the moment of decision is very clear then, and not so most other times...
a friend asked me the other day, "when you come to a fork in the road what do you do?" my reply seems typical, judging from the posts here:
'i walk on both paths as long as possible and at the last second choose the one thats prettiest.."
as i get a little older, the prettiest path is increasingly the more challenging path, so i guess thats a good sign.
at the same time, being pretty evenly J as well, i get pretty settled on a course of action right away sometimes, and it can be hard for me to open up to other options...
what a blessed mess !

So far, the couple of INFJ's I know cause a small line of static upon interaction sometimes.....
Kinda frustrating to me...

But yeah..... there's definitely attraction there...
