"Old age comes on suddenly, and not gradually as is thought." Emily Dickinson
The core of all my writing was probably the five free years I had there on the farm. […] The only thing we had was time and seclusion. I couldn’t have figured on it in advance. I hadn’t that kind of foresight. But it turned out right as a doctor’s prescription.
