Who said “If a writer has to rob his mother, he will not hesitate; the ''Ode on a Grecian Urn'' is…”?

“Writers are always selling somebody out.”

“It's very hard to be a gentleman and a writer.”

“I'd rather be a lightning rod than a seismograph.”

“Writing is turning one's worst moments into money.”

“A professional writer is an amateur who didn't quit.”

“I believe that man will not merely endure; he will prevail.”

“My own experience has been that the tools I need for my trade are paper, tobacco, food, and a little whisky.”

“... maybe the only thing worse than having to give gratitude constantly all the time, is having to accept it.”

“All of us failed to match our dreams of perfection. So I rate us on the basis of our splendid failure to do the impossible.”

“The artist doesn't have time to listen to the critics. The ones who want to be writers read the reviews, the ones who want to write don't have the time to read reviews.”

“The artist is of no importance. Only what he creates is important, since there is nothing new to be said. Shakespeare, Balzac, Homer have all written about the same things, and if they had lived one thousand or two thousand years longer, the publishers wouldn't have needed anyone since.”
