A clear label is often a quiet favor to a future tired person.

Labels are written by someone with full context and read by someone with none. Whoever opens the box, the jar, the folder, or the cable drawer later is usually rushed, tired, or unfamiliar, and every guess you leave behind becomes their small delay. Ten seconds of writing can remove ten minutes of searching, sometimes for a stranger and sometimes for you at your worst hour.

Pick one place where you already know things go unlabeled and fix it today. Write what a tired person would need, including the date and the obvious detail you assume everyone knows. Assume the reader has no memory of you.
