"You don't do all the writing at your desk. You do it elsewhere, carrying the book with you. The book is your companion, you have it in your mind all the time, running through it, alert for links to it. It becomes your chief companion, in the real sense of the word, you can talk to it quietly. It becomes your sole companion" (James Salter, The Art of Fiction, p. 76).
"There comes a time when you realize that everything is a dream, and only those things preserved in writing have any possibility of being real" (Salter, p. 77).
