i'm not completely sure i'm ENFj, but i do know that my doubts GET IN THE WAY of making a good decision. when i make a decision based on my inner knowing, it HAS ALWAYS been the exact right one in the end.
everything you've said here sunshine lively sounds Ne to me.
as rationals, we're not that good with keeping options open, we like closure and doubts get in the way of closure, which actual make us feel more anxious, etc... at least for me...
i do keep my options open until the exact moment that the closure is needed. and then, bam, that's when i make a strong decision. the only way i've found to get rid of doubts is to make that strong decision and MOVE ON, move on, turn my direction to something completely different or i'll keep looking at the decision and doubting again.
i know that this whole figuring out my type thing is very nerve racking for me. i just need to say I AM THIS and not come to this board anymore, move in a new direction or i'll go on doubting whatever decision i made.
