Beauty does not need usefulness to justify attention.

A field of light on a wall does nothing for you. It produces no output, solves no problem, and is one of the better parts of being alive. The demand that everything earn its place through utility is a habit of a particular kind of economy, not a truth about what matters.

Give some part of your week to something with no function at all. Music you just listen to, a walk with no destination, a thing kept only because it is lovely. Its uselessness is the point and it will still change the texture of your days.
