Keep your work desk productive.

De-clutter your work desk regularly, getting rid of things you don't actually use. This includes equipment, paper, plants and even furniture that's doing nothing. Put misplaced items back to their designated space. Designate spaces for supplies and references if you haven't already. Free nearby spaces which are cluttered with things you don't actually use. Put those things out of reach, fill the space with other things.

A good idea is to remove every single item on your desk and think about what you actually need. Repeat this monthly. Put everything back to its place at the end of the day. Repeat this daily. If you find that you need to fetch something daily, put it closer.
