However, I have this book addresses one small(?) problem, writers block for your thesis, with some generally useful strategies
Writing Your Dissertation in Fifteen Minutes a Day: A Guide to Starting, Revising, and Finishing Your Doctoral Thesis
Her most useful advice, and the title of the book, is to do a little bit every day. Even if it is only 15 minutes. Of course if you only do 15 minutes a day, every day, your grandkids may convocate before you, but I like the principle.
Her second most useful advice, is to "Write first." We grad students have the tendency to make a million variations on the statement "I'll read one more book then I'll start writing" or "I'll run one more experiment" or I'll do one more interview", or "I'll check one more fact." Joan Bolker is right, by this point in the game there is enough knowledge in our heads that we can start writing, at least for 15 minutes. Write when you first sit down...go do your other work later in the day. To me, this is the academic equivalent of eating our brussel sprouts first so they are out of the way.
Anyway, the book is an easy read (particularly after reading someone like Foucault, which is when I first read this book), and short (one or two good long trips to the bathroom and you could have the thing finished). I also like that these are more suggestions than rules, she isn't trying to be the Doctor Phil of writers block, just provide tools to help us figure out some healthy writing strategies. She also has some strategies on revising, but I can procrastinate on discussing those for a bit.
Here is the amazon link, give it a looksee http://www.amazon.com/Writing-Your-Dissertation-Fifteen-Minutes/dp/080504891X
If nothing else it gives you one more book to add to your "I just have to read one more book then I can start writing" list
