the book you write is real

What’s in your head is seemingly infinitely richer than what you finally get down on the page. I think that’s why some people never actually get the writing done. They have a dream of a book in their head, and every attempt to write it down feels impoverished. The difference used to bother me until I thought about what the tradeoff was. The book in your head may be the platonically ideal book you could write, while the book you do write may seem a poor beast indeed, Caliban to your ideal book’s Prospero. But the book you write is real. And when you finish, you can hold it in your hands.
