“Not-writing is a good deal worse than writing.”
“You can't write ... on the strength of influence. You can only write a good story or a good novel by yourself.”
“If you can't write, keep trying. If you can't read, ask for help.”
“...no good writing flows from a polluted well - you can write about monsters, but you can't be one...”
“When I'm writing I can write anywhere; when I'm not writing I can't write anywhere.”
