No job is beneath you when you do it like it’s your name on the building.

The status of a job and the standard of the work are separate, and only one of them is under your control. Doing something well when nobody expects it changes how you are seen, and more importantly it builds the habit of caring about output regardless of the audience. That habit follows you into every role afterwards.

Pick the least glamorous task in your week and do it properly, all the way through. Notice what changes in how you feel at the end of the shift. People get offered things for behaving that way before anyone asked.
