I'm wary of advice that doesn't generalize.
I'm wary of advice that does claim to generalize. Giving good advice is a hard problem, partly because it's so context-specific. Yes, there are general principles, but there are tons of exceptions, and even quite similar situations can trigger these exceptions.
Kant got into this kind of problem with (the first formulation of) the categorical imperative. There are many things that are desirable if some people, but not everybody, does them -- say, learning any specific skill or filling a particular social function.
What's difference between the nurse who should leave in order to take meta-level responsibility, and the nurse who should stay because she's needed as a gear?
There are several bad answers to this, and you're right to be suspicious of them. In particular, feeling like you're special is not sufficient reason to act like you're special.
But different people have different value systems and abilities. If people are given the opportunity to develop their skills (up to the limit of interest and/or natural ability), then they should differentiate their roles based on value systems.
In this case: some people want stability, family, friends etc., and some people want to change the world. (It gets difficult for those of us who want all of the above, unfortunately.) No, you don't get to dictate what other people can do with their lives. But I really think you're in no danger of doing so -- even if you do make a distinction between yourself and other nurses (which is really not arbitrary, as you seem to be afraid it is), you're just choosing your own path, not theirs.

Recursive Heroic Responsibility
Heroic responsibility for average humans under average conditions
I can predict at least one thing that people will say in the comments, because I've heard it hundreds of times–that Swimmer963 is a clear example of someone who should leave nursing, take the meta-level responsibility, and do something higher impact for the usual. Because she's smart. Because she's rational. Whatever.
Fine. This post isn't about me. Whether I like it or not, the concept of heroic responsibility is now a part of my value system, and I probably am going to leave nursing.
But what about the other nurses on my unit, the ones who are competent and motivated and curious and really care? Would familiarity with the concept of heroic responsibility help or hinder them in their work? Honestly, I predict that they would feel alienated, that they would assume I held a low opinion of them (which I don't, and I really don't want them to think that I do), and that they would flinch away and go back to the things that they were doing anyway, the role where they were comfortable–or that, if they did accept it, it would cause them to burn out. So as a consequentialist, I'm not going to tell them.
And yeah, that bothers me. Because I'm not a special snowflake. Because I want to live in a world where rationality helps everyone. Because I feel like the reason they would react that was isn't because of anything about them as people, or because heroic responsibility is a bad thing, but because I'm not able to communicate to them what I mean. Maybe stupid reasons. Still bothers me.
