As I sit at my desk in mid-afternoon today yawning, I can't help but be reminded of a story I heard not too long ago.

When Warren Buffet walked into the investment bank offices of Salomon Brothers back in the early 1990’s to help them straighten out a huge dilemma, he reportedly looked around the boardroom and admonished, “You guys look exhausted. Why don’t you go home and get a good night’s rest and we’ll meet again tomorrow.”

Your brain dramatically overreacts to negative experiences when you are deprived of sleep according to a joint study by Harvard Medical School and the University of Berkeley. I often ask my kids how they slept the night before when they're grumpy, but this goes way beyond crankiness. Could it be that problems like depression, anxiety and just plain unhappiness derive from the fact that people just aren’t sleeping enough?

I know that I make many more mistakes when I'm tired, which is to be expected almost, but I also find myself being more defensive about everything. And when I get a good night's sleep? I'm am often so on my game is scary.  So flip that light and shut that TV off sooner and get some quality Zs!
