Who said “... maybe the only thing worse than having to give gratitude constantly all the time, is…”?

“The public have neither shame or gratitude.”

“Revenge is profitable, gratitude is expensive.”

“One can never pay in gratitude; one can only pay ''in kind'' somewhere else in life.”

“Gratitude is one of the least articulate of the emotions, especially when it is deep.”

“If you pick up a starving dog and make him prosperous, he will not bite you. This is the principal difference between a dog and a man.”

“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.”

“If a writer has to rob his mother, he will not hesitate; the ''Ode on a Grecian Urn'' is worth any number of old ladies.”

“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.”
