Several delusions weaken the writer’s resolve to throw away work. If he has read his pages too often, those pages will have a necessary quality, the ring of the inevitable, like poetry known by heart. They will perfectly answer their own familiar rhythms. He will retain them.
Every year the aspiring photographer brought a stack of his best prints to an old, honored photographer, seeking his judgment. Every year the old man studied the prints and painstakingly ordered them into two piles, bad and good. Every year the old man moved a certain landscape print back into the bad stack. At length he turned to the young man: “You submit the same landscape every year, and every year I put it in the bad stack. Why do you like it so much?” The young photographer said, “Because I had to climb a mountain to get it.”
(Annie Dillard, The Writing Life)
