This is a paraphrased quote from the main character of the Cohen brothers' film, Barton Fink. Full quote below.
"I've always found that writing comes from a great inner pain. Maybe it's a pain that comes from a realization that one must do something for one's fellow man to help somehow ease the suffering. Maybe it's personal pain. At any rate, I don't believe that good work is possible without it."
