Poor sleep and a lack of sleep really affects all aspects of my life. When I get enough sleep, then I get more done, I'm more active, I eat better, I make better decisions, I cook better meals, I enjoy my life more. If I'm tired, then it's all quite the opposite!
I find it really important to have a good bedtime routine. I wind down for at least an hour, before sleep. My pillow may be my most important ally in a good sleep. I also track my hours of sleep on SP "Other Goals", to remind myself daily, of the importance of adequate sleep.
