Now you've finally said it: SP gut logic. Historically, I have observed that different personalities create intelligence in their own image. For the sensing cleaning lady, you can expound on Tolstoy's War and Peace, and she may hear you out (likely zones out) but assigns no value to your analysis in terms of intelligence. But if you can figure out how to rearrange the dishes in the dishwasher so as to fit more in, well then you're a genius.
There have been many occasions in my life where I have been recognized or rewarded for doing something trivial or mundane. Usually some rote, repetitive crap that is absolutely mind numbing. Conversely, some of (what I feel) were my most brilliant moments usually go completely unrecognized. Apparently, most of the world does not crave what makes me tick.
The biggest problem is figuring out when you have to be on, and when you just have to shut the Ne off. I think that's why ENTPs seem more introverted than most Es - often, the only time we can extravert in our natural way is by ourselves. Sometimes, I don't want to have to convince another person to go along with my impulses, though I would prefer having them there - I'll get plenty out of doing it myself.
I think this is also a big source of struggle, that is, that you never seem as naturally energized as other types, due to the need to constantly suppress that impulsive nature in social contexts. It's also hard to not be able to seize upon every interesting thing that arises, and just go along with the pack.
