Writing and reading decrease our sense of isolation. They deepen and widen and expand our sense of life: they feed the soul. When writers make us shake our heads with the exactness of their prose and their truths, and even make us laugh about ourselves or life, our buoyancy is restored. We are given a shot at dancing with, or at least clapping along with, the absurdity of life, instead of being squashed by it over and over again. It's like singing on a boat during a terrible storm at sea. You can't stop the raging storm, but singing can change the hearts and spirits of the people who are together on that ship.

E.L. Doctorow said once said that 'Writing a novel is like driving a car at night. You can see only as far as your headlights, but you can make the whole trip that way.' You don't have to see where you're going, you don't have to see your destination or everything you will pass along the way. You just have to see two or three feet ahead of you. This is right up there with the best advice on writing, or life, I have ever heard.
