And how do you "manage" them, my lovely? I know what NFJs are capable of, good and bad, and that we live under a shroud. I tend to channel my, shall we say, less than stellar attributes into something I hope will be better than just giving them free rein. What do you do to contain/train/sublimate those impulses?
Way I see it ENTPs can be champions and villains at the same time, those two parts are inter-merged. Comes down to perspective as to what is right in a situation. I know personally I'm probably capable of doing things that could be seen as villainous by others if it was justified in my head, but at the same time I have a strong desire to put humanitarian needs above all else.
Figuratively speaking, I could kill one to save many. And I would sleep at night fine.
And this why we shall never divorce!

haha!
Can you elaborate on that for me? I know that tertiary Fe in ExTPs can be quite a force, almost on par with Fe primary ExFJs. I've always wondered why that is.
People are the ultimate feedback machines. They give me inspiration.
ENTPs: Do you find that your dom Ne leads to you making stuff up just for fun? -- and do you lie well (even if you don't lie often)?
I make stuff up for fun a lot, the more unbelievable and absurd the fable, whilst still being eaten up by my audience, the better. It never ceases to amaze me how many people will take me seriously when I say something outlandish. Of course the punch line isn't funny unless I explain I'm being absurd so people will know in the end that I'm being stupid.
Lying though is a whole other game and one I prefer not to partake in, firstly and rather importantly I do not have a good memory, remembering the truth is hard enough, having to remember two versions of the story is stupid, secondly I highly value honesty and the ability to be forthright and lastly I do not feel good about fibbing, I'd rather say nothing, or tell the blunt truth and deal with the consequences.
Do you like jumping from topic to topic when having a friendly conversation?
Not really, the way you suggest that sounds rather stop-starty. I like flow, letting the conversation go where ever both parties want it to without silent time in between that is clearly filled with both people desperately racking their brains to think of something to say to fill the silence. Flow. Ne finds the link between topics so no jumping is required.
