I think the top tip I've learned so far is that you should never finish a day's writing at a convenient point, like the end of a chapter, or a conversation, or whatever. Because if you stop while you've still got some writing in your head to put down, that's how you can get back into it tomorrow. If you foolishly stop at the end of a chapter, say, then you've got to start the next one completely cold the next day.
Favourite line of the day:
