Sitting on the edge of the bed.
In more practical terms, when I find myself sitting on the edge of the bed. I now know if I'm expecting myself to climb in it or get up and face the day...
In spiritual terms I also know the answer to the Zen koan, 'What is the sound of one hand clapping?'
Both of which are a marked improvement from my performance as 'a high functioning alcoholic' in my drinking days....
