The best way is always to stop when you are going good and when you know what will happen next. If you do that every day … you will never be stuck. Always stop while you are going good and don’t think about it or worry about it until you start to write the next day. That way your subconscious will work on it all the time. But if you think about it consciously or worry about it you will kill it and your brain will be tired before you start.

I never come back to a blank page; I always finish about halfway through. Hemingway taught me the finest trick : “When you are going good, stop writing.” You don’t go on writing and writing until you come to the end of it, because when you do, then you say, well, where am I going to go next? You make yourself stop and you walk away. And you can’t wait to get back because you know what you want to say next.
