On Writer's Block

This has to be my favorite book on writing and I've read it at least three times in as many years. Victoria Nelson lays out the anatomy of the blocked writer, inch by inch, the bare corpse split open on the table before us. The three overarching themes of the book are:

(1) the tension between authenticity and ambition

(2) the truly complex nature of the beast; there is not one block but many, their shapes varied and causes many

(3) a block is not a curse but a blessing, a message from the creative self, whence the writing comes
