Space is at a premium in the home office, so being productive and effective hinges on organizational skills. Keep office supplies, such as printer paper, envelopes, and other items together in one designated area. You don't want them migrating out of your office and into the rest of the house!
Additionally, keep your workspace, however large or small it may be, neat. It doesn't have to be spotless while working, but keep on top of clutter. The easiest way to keep your workspace neat is at the end of each workday. At that time, clean off your desk or work space and prepare for the next day: list calls to be made, appointments you have, etc.
