Spring is in the air and cherry blossoms and magnolias are in full bloom in my neighborhood. As the days get longer, so do my To-Do lists. The sunny skies and warmer weather entice me to stay up as late as I can. And, it takes tremendous will power to turn off the lights and go to sleep while daylight lingers a bit longer each day. Yet, I have learned over the years, that I need to get eight hours of sleep to be healthy and productive.
