I know it's a stretch for an INTP to advise a bunch of ENTP's on the use of Ne, but I sometimes conquer (or side-step?) this stuff by using even MORE Ne. I'll come off as the guy who is always cheery, always optimistic, always has a funny joke to tell, almost apathetic to all the rules, structure, stifling-ness, and "the man". Like I'll just put on this face like I'm just "gliding right through it all" and having a ton of fun along the way. I mean, in the workplace, I still have to get my work done (if I want a job) - I can't be a complete moron who doesn't conform to anything, but I find that I have an ability to be so optimistic, that I just don't let it all bother me much. I still tell my jokes, I still act like a goofball, I still make people laugh - I sort of make it known that I am outside the box. If they choose to stay in it, that's up to them, but I'm going to live life outside of it and refuse to be stifled by it.
I totally relate to the OP - I know it can happen sometimes (feeling stifled) - I'm just saying, maybe fight it with even more Ne. Just be the smart, whacky, witty, funny, absent-minded professor guy and people will learn to give you that space - they will learn that you aren't a conformist and there are certain things that they'll have to deal with when they do business with you. Professional and effective, yet a free-thinker and outside the box.
