There are a few ways to approach work: 1) you show up, do your job, you do it efficiently—sometimes even faster than expected—and leave. 2) you create change, make an impact in unmeasurable areas, fail, and solve interesting problems.
Doing your job the first way can be enough. It is, after-all, what you were hired to do. But they could hire anyone with your experience to do that. What will make you irreplaceable?
What will we miss? To answer that question you’ll have to stop thinking about the job description and start considering your own mission, your own point of view, your own platform.
Another question you’ll have to keep in mind is whether or not your organization even values that kind of thing.
