I've long known that if I needed to "be creative" the best thing to do was to take 1) a shower, 2) a napa 3) a walk. Best, but not necessary, would be to do all three. In the words Daniel Goleman, author of Emotional Intelligence we need times of "open awareness" to be receptive to seemingly unrelated ideas.
I came home from a fantastic New Year's Eve yesterday with big plans to Get Things Done. Instead, I took a nap, ate a year's worth of chips and salsa and binged on The Killing, Season 3.
My only regret was that it took me till halfway through the chips and salsa before I decided to just go with it and not feel guilty. Do as I say not as I do, go for it, even if that means A Big Long Rest.
