"The most extraordinary thing about the oyster is this. Irritations set into his shell. He does not like them. But when he cannot get ride of them, he uses the irritation to do the loveliest thing an oyster ever has a chance to do. If there are irritations in our lives today, there is only one prescription: make a pearl. It may have to be a pearl of patience, but anyhow, make a pearl. And it takes faith and I love to do it."
