"I heard a famous author say once that the hardest part of writing a book was making yourself sit down at the typewriter. I know what he meant. Unless a writer works constantly to improve and refine the tools of his trade they will be useless instruments if and when the moment of inspiration, of revelation, does come. This is the moment when a writer is spoken through, the moment that a writer must accept with gratitude and humility, and then attempt, as best he can, to communicate to others. A writer of fantasy, fairly tale, or myth must inevitably discover that he is not writing out of his own knowledge or experience, but out of something both deeper and wider. I think that fantasy must possess the author and simply use him. I know that this is true of A Wrinkle in Time. I can’t possibly tell you how I came to write it. It was simply a book I had to write. I had no choice. And it was only after it was written that I realized what some of it meant. Very few children have any problem with the world of the imagination; it’s their own world, the world of their daily life, and it’s our loss that so many of us grow out of it."
