I was told that as a young boy I had rather quick reflexes and seemingly awesome hand-eye coordination. I would apparently catch butterflies out of the air by their wings, but gently enough to let them go without harming them.
I always thought I had a fairly slow reaction speed, but the past couple years have shown me that I have exceptional reflexes. I figured out that, most of the time, my brain was busy overanalyzing the situation, as my eyes would flawlessly watch everything unfold. So I decided, why not shut my brain up and focus on whats at hand instead?
So without knowing it, I learned something that jet pilots do called "emotional compartmentalization"... In fact, I may have mentioned it once or twice before. Basically, I basically can 'slow down' my perception to increase reaction speed. It's like watching a movie in slow-mo with commentary by my Ni.
So what kind of crazy unexpected things can you do? What kind of natural skills do you have that you think are atypical of the average INFJ? What skills do INFJs lack that you feel they could use?
