Someday your current job will be a line entry on your resume. Under the entry, you’ll have two or three bullets to describe your major accomplishments. “Did a good job of doing what always was done” can’t be one of them.
There is a lot of power in reflecting at the beginning of a new job on what you want the two or three bullets to be, and deliberately setting about building them over the course of your job tenure. Otherwise, you run the risk of having them simply be the incidental byproduct of what opportunities happened to come your way.
