W. Somerset Maugham said this quote

He accepted the deformity which had made life so hard for him; he knew that it had warped his character, but no he saw also that by reason of it he had acquired that power of introspection which had given him so much delight. Without it he would never have had his keen appreciation of beauty, his passion for art and literature, and his interest in the varied spectacle of life. […] Then he saw that normal was the rarest thing in the world. Everyone had some defect of body or of mind […] The only reasonable thing was to accept the good of men and be patient with their faults.
