A lighthouse’s usefulness does not depend on whether anyone finds it beautiful.

Usefulness and admiration are independent of one another. A thing can be entirely unappreciated and entirely load-bearing, and no amount of indifference reduces what it is doing. Much work is like this, especially the kind that keeps other things running: nobody photographs it, nobody discusses it, and everything would stop within a week without it.

If what you do is not the sort that gets praised, the lack of praise is not a verdict on the value. Keep the standard where you set it. Then look for the unglamorous load-bearers near you and say something specific to one of them about what they hold up.
