Jeanette Winterson said this quote

There was a man here, lashed himself to a spar as his ship went down, and for seven days and seven nights he was on the sea, and what kept him alive while others drowned was telling himself stories like a madman, so that as one ended another began. On the seventh day he had told all the stories he knew and that was when he began to tell himself as if he were a story, from the earliest beginnings to his green and deep misfortune. The story he told was of a man lost and found, not once, but many times, as he choked his way out of the waves. And the night fell, he saw the Cape Wrath light, only lit a week it was, but it was, and he knew that if he became the story of the light, he might be saved. With his last strength he began to paddle towards it, arms on either side of the spar, and in his mind the light became a shining rope, pulling him in. He took hold of it, tied it round his waist, and at that moment, the keeper saw him, and ran for the rescue boat.
