Take the job nobody wants and you’ll learn what nobody else bothered to.

Unwanted work is uncrowded, and uncrowded is where you get to actually do things. The task everyone avoids usually teaches the part of the process nobody else understands, which is exactly what makes you hard to replace later. It rarely looks impressive while you are doing it. That is the reason it stays available.

Volunteer once for the thing the group is quietly hoping somebody else takes. Do it properly, and pay attention to what you learn that the others now have to ask you about.
