"I am writing shorter and shorter novels," he says. "My commitment to this is no different than my exercise routine or my decision to give up drinking beer. I am aware of the limitations of aging. And there is nothing more important to the novelist than the preservation of memory. My grasp of fictional detail and chronological story is worsening, so I must work with what I have to make sure I’m fully cognizant of what I’m creating."
Or, as Clint Eastwood said (Harry Callahan): “A man’s got to know his limitations.”
