Keep at it! The one talent that's indispensable to a writer is persistence. You must write the book, else there is no book. It will not finish itself. Do not try to commit art. Just tell the damned story.
Things rarely happen for a single reason. Even the cleverest and most skilled manipulators recognize that their real art lies in making use of that which they cannot predict.
Books and movies are different art forms with different rules. And because of that, they never translate exactly.
