I've been working on this paper for some time, and it's become clear that if I'm to finish it by the deadline I must make a dogged effort to devote time to writing it regularly: writing occasionaly for hours at a time hasn't been working for me. Today is the first day. I intend to do an hour a day for five days a week, no matter how productive it feels, until it's done. I may vary the plan as I go, but that's it for now. Advice?
