That was Don DeLillo's straight-shooting antidote to writers suffering block.
I've been thinking . . .
"A non-writing writer is a monster courting insanity."
"The craft or art of writing is the clumsy attempt to find symbols for the wordlessness. In utter loneliness a writer tries to explain the inexplicable. And sometimes if he is very fortunate and if the time is right, a very little of what he is trying to do trickles through--not ever much. And if he is a writer wise enough to know it can't be done, then he is not a writer at all. A good writer always works at the impossible."
