Forgetful
I don't know about other INFJs but I have very different "modes" for operating...I know that all types do this to some extent and all types have various drives they work with...however, in my experience with many INFJs, the INFJs tend to be very accentuated this way...
Being watched / "I'm on"
- this is super agent mode and I am very, very, very, very "on"...I forget nothing and I am extremely intolerant of those who do...this is my "move fast, hit hard" mode...this is very taxing and I only use it for breif periods...so I often go into this mode "before leaving"...and again "upon returning to the lair"...this has become a habit over the years...I also can go into this mode instantly when needed...but it is EXPENSIVE for me internally...
In the presence of spiffy Ns / "engaged"
- when this happens I can "surf" the energy of the people...this gives me much more energy and I can stay "out" for much longer....when this happens I gain power but I lose control correspondingly...my attention to details is limited mainly to the peeps I am focused on...and many of these details will start to become abstract the more into the person I am...usually I don't appear/feel scatter-brained...just very "into the conversation/moment"....I do tend to shave lots of corners in this mode...both physical and social...but it is usually seen as charming and a strength...however, I can't do even this for too long...longer than the sensing but not "long"
Incongruencies / "podering"
- when there are incongruencies between whatever Ni framework I left the lair with and what is happening in the field (Fe & Se)...then I ponder this with my Ti...I have learned that i SHOULD NOT do other E stuff while doing this process...and also there should be no mental "multi tasking" with E stimulus...my Ti is ability by it's nature gains strength as I stop moving, stop interacting, stop everything and just think...if I am forced to "move" at this time, I will appear EXTREMELY clumsy...if I am forced to interacte at this time, I will appear EXTREMELY scatter-brained...obviously I usually do Ti in my lair but it still comes up sometimes on the outside...I have learned also that people almost always misinterpret Ti done in plain view as something it is not (bored, angry, dismissive, arrogant, etc)
Tank is low / "escaping"
- when I've been "out" to long I will start to feel an irresitable pull back to my Ni world...when I've got my life organized well peole can't ever tell...friends who have known me for 5, 10, 15, 20 years have no idea...unless I want them to...but sometimes you get caught out...it happens....then it's almost like I'm "on drugs"...I mean totally effing spacey....I don't notice where I am walking...people's conversations flow in and out of the ones I am having in my head...at these times I become DANGEROUSLY clumsy and DANGEROUSLY scatter-brained...I am also very very cranky...crankiness helps back people off...which when an INFJ gets to this point out in the open is a necessary safety precaution for our inner selves....
Sorry if I went on too long but I wanted to articulate that I have zero continuity in this area...It's like their are several people in me...some are very coordinated, some are not...some are very focused, some are not...
