Me: high Ni, not so great Te (hence the lowercase j - for some reason I still feel like NT, but it's the dealing with the outer world that indicates weak Te. This is less about the abstract thinking Ni-Te team than about Te in everyday life)
To me, using Te is often very exhausting, but also quite rewarding at times. I have this tendency to hoard stuff I have to do and make it a Te day and inevitably, I'll curse the advent of such days. On the other hand, I also have really productive days during which I get a load of stuff done and that seems to energise me. All in all, I would say that I turn on the Te engine very reluctantly, but then run with it quite nicely for a certain amount of time. I notice that I'm more Ni-Te during the day and more Ni(-Ne) at night or during holidays etc...it is my preferred modus operandi and the more whimsical and free Ni(-Ne) combination is more energising than the Ni-Te one, but I can only operate in it when the constraints of everyday life have been met with Te.
I guess it's a bit of a necessary evil to me in this capacity.
