Kafka on the Shore

by Haruki Murakami

And once the storm is over you won’t remember how you made it through, how you managed to survive. You won’t even be sure, in fact, whether the storm is really over. But one thing is certain. When you come out of the storm you won’t be the same person who walked in. That’s what this storm’s all about.

There’s only one kind of happiness, but misfortune comes in all shapes and sizes. It’s like Tolstoy said. Happiness is an allegory, unhappiness a story.
