Extraordinary mind fog this AM, returning in the afternoon, after I burned off the morning banks with the reading.
Possibly physical/contagion, coming off of a few days of rare congestion and fatigue; possibly the weather, as the winter cold and winds returned last night.
It's a bit like a painter fighting off blindness -- bold, strong strokes of the mind might help to clear the fog, but they don't always serve the work itself, or the day.
