I’m reading Annie Dillard’s The Writing Life. It is beautiful.
“When you are stuck in a book; when you are well into writing it, and know what comes next, and yet cannot go on; when every morning for a week or a month you enter its room and turn your back on it; then the trouble is either of two things. Either the structure has forked, so the narrative, or the logic, has developed a hairline fracture that will shortly split it up the middle—or you are approaching a fatal mistake. What you had planned will not do. If you pursue your present course, the book will explode or collapse, and you do not know about it yet, quite.”
