George Costanza's Tips for Working Hard

Never walk down the hall without a document in your hands.
People with documents in their hands look like hardworking employees
heading for important meetings.
People with nothing in their hands look like they're heading for the cafeteria.
People with a newspaper in their hand look like they're heading for the toilet.
Above all, make sure you carry loads of stuff home with you at night,
thus generating the false impression that you work longer hours than you do."
