Human beings are remarkable - at what we can learn to live with. If we couldn't get strong from what we lose, and what we miss, and what we want and can't have, then we couldn't ever get strong enough, could we? What else makes us strong?
John IrvingAlong the (writing) way accidents happen, detours get taken... But these are not "divine" accidents; I don't believe in those. I believe you have constructive accidents en route through a novel only because you have mapped a clear way. If you have confidence that you have a clear direction to take, you always have confidence to explore other ways; if they prove to be mere digressions, you'll recognize that and make the necessary revisions. The more you know about a book, the freer you can be to fool around. The less you know, the tighter you get.
