Do your job; be the best at whatever your job description is.

My job description is... being enthusiastic.

Being a caregiver for your child is part of the job description of being a mammal.

Voyeurism is a director's job description. It's an artist's, too.

It's definitely part of my job description not to be too fat.

Nowhere in the job description of an artist is the requirement that I must validate your taste.
