If I had eight hours to chop down a tree, I’d spend at least two hours sharpening my ax. YOU are your ax! After a while you will wear out if you don’t take care of yourself. YES, everybody needs something and yes, YOU have to do it … but who will do it if you are DEAD? Take care of yourself. The reason you may feel tired, overwhelmed and irritable is not so much because of what you’re doing, but because you’re doing it with a dull axe. Don’t expect people to automatically know to value and appreciate you. Some will never know how until you train them based on how YOU value you. You’re important too, so begin acting like it.
