Ernest Hemingway in his 1954 Nobel Prize speech:
Writing, at its best, is a lonely life. Organizations for writers palliate the writer’s loneliness but I doubt if they improve his writing. He grows in public stature as he sheds his loneliness and often his work deteriorates. For he does his work alone and if he is a good enough writer he must face eternity, or the lack of it, each day.
You got that right, Papa.
Via Andrew Sullivan.
