I do relate to it in many ways. Sometimes, I just feel awkward amongst people. I want to keep away and am reluctant to approach people. but yet, I don't want to be a complete outsider. Kind of living in my own little weird world. I don't want people cutting in on my inner world but sometimes, part of me does want to get it out there. I guess sometimes peopling doesn't come naturally. My people need isn't horribly strong 100% of the time but I would hate to loose the people who I have let in.
Ni is indeed a perceiving function but we still have the J going for us. Some INFJs may not even look J but our J catches up with us sooner or later. Some people, the J barely even manifests, others you can see it more. I do have some perfectionistic tendencies, more for myself and my work than on others. I can be particular about getting things done that I need to get done and going the extra mile on the work I do. Also about where my priorities are exactly. if I don't do that, it just seems incomplete. I often need a week or many days to be alone and hate people intruding on this time. Even when it's been for hours or days.
I'm often coming up with ideas for things, they come at the most random time and can't be forced. So many ideas, so little time which is why it's good to strike while the iron is hot. I kind of multitask on the various ideas that spawn. I'm slow at producing but am proud when I get around to making them reality. I also like to pick things apart and look deeply into things.
I would say I myself am just messy, not so much tidy. I do tidy up but when I do get around to cleaning, those skills had to be learned. My belongings go into chaos if I don't keep on top of them. Mess doesn't bother me terribly but super neat freaks get bad first impressions of me because of what a mess I am. It's one thing that's evident to people off the bat.
