Personally, I think they're just not go-getters (your
  co-workers).
  Thing is, there's systems within systems.
  I've had complacent co-workers. I wasn't one of them. I had my
  own agenda that I allowed to match up with the authorities when
  it suited me.
  Was I fooling myself? No.
  I crossed departmental lines to help people outside my
  department, even competing departments because MY AGENDA was to
  assist people to Betterment; whatever it was. [in that case, it
  was helping them get to a point where they could use Excel and
  other data tools to do their own reports, be better at their
  jobs, and help the organization as a whole... but mostly.. to
  help them as people.

  Someday they may leave that job.
  Their skillset remains.
  I helped.

  Some people's mission is just "get through the day because there
  is a beer waiting at home." And that's fine. Everybody has
  goals, even if they're unspoken.
