If you're like many people, your desk probably acts as the kitchen table for your office. It's the place where everything gets dropped, and pretty soon you have to dig to get to your computer. A clean desk will guarantee more productivity, but you're already so busy trying to be productive, who has time to stop and clean? The key is to schedule it daily, and treat it like it's a meeting you can't miss. It helps if you minimize the tchotchkes and picture frames and only keep work essentials on, in and around your desk.
