Two of the nine summer book writing groups for faculty have yielded the same tidbit of writing advice that they heard "somewhere." It goes like this. When you're having a great writing day and the time you allotted for writing is up, instead of going on and on until you burn out, stop your work while you're still on a roll, and leave yourself notes for where to pick it up the next day. Then you'll be excited and eager to return to the task, and you'll have a much better time getting started.
Hmmm. Has anyone heard this before? Any idea where it comes from? And does it work?
A completely lazy web search yielded these links about it, and suggest that it may come from the book Writing Your Dissertation in 15 Minutes a Day:
