Declutter Your Workspace in One Afternoon

Most desk cleanups fail the same way. You start with the surface, get distracted by a drawer of old cables, spend an hour deciding whether to keep them, and by the end the desk is somehow worse than when you started. The trick is to do it in the wrong order on purpose — surface first, drawers second, decisions absolutely last.
Before anything else, take one photograph of the desk as it currently looks. It is a small thing and it feels silly, but you will refer back to it more than you expect.

Clear the entire surface into a single pile on the floor. Wipe the desk down. Now put back only the three or four items you actually used yesterday — a notebook, one pen, the mug you were drinking from, the charger you plug in each night. Everything else stays in the pile for now.
This step is the hard one because it feels wasteful to touch items twice. It is worth it. A desk with three things on it will hold your attention differently than a desk with fifteen.

From the leftover pile, sort in three passes: trash, donate, "put away somewhere else." Do not create a fourth pile for "maybe." A maybe pile is how you end up right back where you started in six weeks.
The final step is the one people skip: schedule a fifteen-minute reset in your calendar for next Sunday. A clean desk is not really an event, it is a small recurring maintenance job, and treating it that way is more useful than a once-a-year overhaul.
