"I walked slowly out on the beach. A few yards below high-water mark I stopped and read the words again: WRITE YOUR WORRIES ON THE SAND. I let the paper blow away, reached down and picked up a fragment of shell. Kneeling there under the vault of the sky, I wrote several words, one above the other. Then I walked away, and I did not look back. I had written my troubles on the sand. The tide was coming in."
