Comes down to functions, I think.
Ne-Fi-Te (in that order) equals curiousity and enthusiasm in the unknown; sees potential in new experiences on fewer hints than most; has enough Fi passion to assert individualism, but not so much that they want to seclude themselves for long. They are not introverts. That's kind of the point, I guess, on how E/I find meaning and get their energy; and they have the real world smarts to get things done and behave with Te types well. INFPs aren't exactly the same. I can only speak for myself at least. As much as I keep trying to break out, I don't know how to be an extrovert. I don't know how to specialize, "go with the flow", be optimistic in the moment like an ISFP either. And I'm not as well rounded, curious, and enthusiastic like an ENFP (who've got enough ideas for themselves as well as others). I've been stuck in a rut for years. I don't even want to talk about it, but here I am derailing this thread somewhat (sorry!). It's simple enough to say that I'm bogged down by memories and ideals alike. I have other particular issues that probably stack on top of it and I'm not sure how to work through them with just "self-motivation" (like being a diagnosed depressive..and embarassingly, worse than that too. I don't talk about it with most because they end up conjuring up images of lunatics. Which also pisses me off about people.).
That said, sometimes I wonder if my ideas or even general attitude is even applicable outside. And I don't work well with the Te world either. "Why so serious?" Sometimes that's my motto with Te. In the end, it doesn't matter. I proudly diss all of the stuff that bothers me and stay in my rut..just recoiling, with more conviction and reasons to avoid finding a solid place in life. The only thing that keeps me inspired is trying to live up to things I believe, and extending Fi outwards instead of all of this self absorbed shit. I try to love. Not try. I mean, I think I do sometimes. In this way, I start seeming ENFP, but not quite as enthusiastic. Fi-Ne instead of Ne-Fi, I think. I'm at the point right now though that I'm not exactly doing that. It's push and pull.
Ugh.. Surely I'm going to regret this post.
