Jim Harrison, The Road Home:

With age one loses all sense of the supposed inevitability of art and life. Vivid moments are no longer strung together by imagined fate. The sense of proportion in good and bad experience loses its appeal. Bad is bad and you let it go. Good you cherish as it whizzes by. Mental struggles become lucid and muted with particular visual images attached to them, somewhat irrationally or beyond ordinary logic. Money shrinks to money. Fear is always recognizable rather than generalized. It is sharp and its aim is very good indeed. If there is wisdom as such, it is boiled down by fatigue. On the very rare occasion that I check out an old notebook as I am doing now, the sweat rises in my hair roots and I wonder, What is this fool going to do next?
