Yesterday I felt like I wasn't pulling my weight at work. I wasn't hungry and had no energy. I couldn't connect with anyone that I talked with, I was forgetful and I couldn't concentrate. My kids were annoying and demanding, my personal life felt like it was crashing down around me.
Today I felt like competent and useful at work. I had much more energy, had good conversations with people, felt like I had a handle on all the personal stuff I'm dealing with and had a pleasant time with my kids who are funny, entertaining and interesting people. I had a good swim workout and I have the energy to 'blog.
The difference? 12 hours of sleep. It does wonders - everyone should try it once in a while.
