Grinity, great job of describing how the various functions interact with each other. I was almost 100% NF, 51% I and 60% P.
When you mention how Ts differ from Fs,
I think you are ontopic here Jamie, glad that you enjoy typetalk.
Before I try painting a picture, I want to check if the "I" is right. Since you are a P (60% is plenty) then I would predict your Main strength to by your "N" - so it fits that you are a "I" if the 2nd strenght of "F" is what is shown to the world, and the "N" is held inside. Which strength to you feel is your earliest/best? The N or the F?
2nd way to test I vs. E, is 'if you were feeling low, and needed more energy, would you be alone or seek out beloved people to recharge?
Lets figure out the I vs. E question first -
