Naps are great for health and productivity. Still, deep down,
many of us feel like slackers for sleeping at work, which makes it hard
to drift off. Try to clear your mind of this guilt and focus on the
positive aspects of your choice. Know that you're in good company. Some
of the world's greatest achievers were/are nappers, including Albert
Einstein, John F. Kennedy, Winston Churchill, Thomas Edison, Lance
Armstrong, and Bill Clinton.
