Bring On the Night If your best work happens in the wee hours, you're not alone.

Around 3 o'clock, you might find Mike Faith sending e-mails or considering a supplier. But Faith, founder and CEO of 55-employee San Francisco headset company Headsets.com, is doing these tasks at 3 a.m., not 3 p.m. The middle of the night "is the most productive work time for me," says Faith, 42. "If someone is around, I've got all his or her focus, and if no one is around, I've got all my focus."

For night owls like Faith, 8-to-5 is now a prelude to the 9 p.m. to midnight (or later) shift when they finally have some quiet time to think, work and plan. "Distractions during the day make it impossible to work on larger projects or [tasks] that require more complex thinking," says Jonathan Kramer, Ph.D., founder of San Diego-based Business Psychology Consulting. At night, he says, entrepreneurs "can do a more effective and efficient job."

Faith--who works into the wee hours at least once a week--often gets quick e-mail replies from other CEOs, and he feels a sense of camaraderie. "There's a special kind of 'Yup, we're working on this when no one else is around' [feeling]," he says.
