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.
Ernest HemingwayYou expected to be sad in the fall. Part of you died each year when the leaves fell from the trees and their branches were bare against the wind and the cold, wintery light. But you knew there would always be the spring, as you knew the river would flow again after it was frozen. When the cold rains kept on and killed the spring, it was as though a young person died for no reason.
Ernest HemingwayOh, now, now, now, the only now, and above all now, and there is no other now but thou now and now is thy prophet.
Ernest Hemingway
