No apologies, I speak Ni well enough (usually) and understood what you were saying.
For me, the closest thing to perfection is a frame of mind that can be had in an instant with an intentional lateral shift in consciousness/Being, mainly revolving around mindfulness, but also incorporating discipline and higher awareness. Think Wim Hoff or David Blaine type stuff (both of whom heavily focus on Ni and Fi, just in opposite orders). It's all about controlling and shaping the abstract or theoretical (which includes the future) self, but it can be brought into the present if you blur the concept of time.
I think the concept and strategies are simple and effective enough, but the real barrier is rather earthly in nature (like suffering, distractions, or mental illness for example).
So for me (even though I suck at following my own guidance here), perfection in theory can be embodied in a moment of intent, no matter where one is, and it can be carried with oneself and used in the form of discipline as a tool to bend one's surroundings and circumstances into a more appealing shape.
But it always comes from within, and so cannot be pursued and captured.
Full disclosure: I do have an image of ideal Me in my head, but I'm still aware that perfection, like manner things (everything?) is a construct. I suppose pathology would be too. It's all relative.
Now who doesn't make any sense?
