This morning I began, at 5:00 am, with a hike up and down the hill in front of my house. I trekked up and down three times with a vigorous feeling, a sense that a stirring day was starting. A few birds were softly whistling, and a car passed occasionally, but mostly it was just the street, the houses, a cloudless dawn sky, and me. Day was arriving, and so, I felt, was another long series of fresh and surprising moments.
