Admittedly, tidying up is never really fun—we realized that as kids when the playroom needed clearing up. But what stuck with us was that the fewer toys there were, the faster the tidying up went. This can also be applied to office cleaning. First get an overview of everything on your desk and in the drawers, and then ask yourself whether you really need it all and, if so, where it actually belongs.
Loose paperwork gets in the way of structured office work—sort out and file away what you still need. For example, all invoices for office supplies should go in one folder and all insurance documents in another. The same applies to pens, erasers and other consumables: Check them, sort them out and store them together.
