YET MORE REASONS TO GET ENOUGH SLEEP
Why now?  Because a lack of sleep can make you, not just sloppy, but unethical:
"As we all know, sleep deprivation can lead to exhaustion-fueled mistakes in the workplace, whether they be a simple typo in a quarterly report or life-threatening errors while operating machinery. (Or as the FAA discovered recently, embarrassing front-page headlines about workers napping on the job.) But according to two business school professors, it can make people more unethical too.
In a forthcoming paper in the Academy of Management Journal, highlighted recently in the Financial Times, Michael Christian of the University of North Carolina’s Kenan-Flagler Business School and Aleksander Ellis of the University of Arizona’s Eller College of Management studied sleep-deprived nurses and students who’d pulled all-nighters in a sleep lab. They found that a lack ofsleep led not just to poor performance on tasks that require “innovative thinking, risk analysis, and strategic planning”—though studies have shown all those to be true—but also to increased deviant and unethical behavior in both groups. Examples included rudeness, inappropriate responses and attempts to take more money than they’d earned.
How does this happen? Christian and Ellis write that sleep deprivation results in lower brain functioning, particularly in the prefrontal cortex, which contains the parts of the brain that control “executive” functions, such as inhibiting emotion and behavior. Sleep deprivation reduces the metabolism of glucose, which acts as brain food for these functions.
And why does this matter for leaders? In a global, always-on work world, responding to emails from the boss at midnight is considered normal and logging four hours of sleep a night to talk to colleagues in Bangalore is a regular occurrence. As a result, going without sleep has become a workplace badge of honor. Staying up all night to crunch on a deadline or taking red eye flights to meet clients on two continents in one day have replaced putting in a few hours on the weekend as evidence that you’re working hard.
The numbers the two professors cite in their paper are startling. According to the National Sleep Disorders Research Plan, sleep deprivation costs the U.S. economy some $150 billion annually in accidents and productivity losses. The percentage of Americans who sleep less than six hours a night has jumped from 13 percent to 20 percent between 1999 and 2009, according to the National Sleep Foundation. The same group estimated that in 2009, one-third of Americans lost sleep thanks to financial distress. Who knows what that number is now."

And I know there are many of us out there with Moebius who work very hard.  Sometimes it's because we love what we do; we're committed to it.  We choose to work hard.  And hey, sometimes maybe you have to.  It ain't always easy when you look and sound different.  Others wonder about you.  It's lke you always have to prove yourself all over again, every day...

But still.  Don't run yourself into the ground.  Take care of yourself.  Not only is it important to those who care about you...but it's also good for YOU.  It will make you a better worker, and get you better at what you do.
