I don't think of it as a block, but only as a bad writing day -- just as there are good and bad days in any profession. So I work through it, I write anyway, and even if the material is junk I am relieved of the guilt of not working. The next day there is something to rewrite, and often I find a thing or two that is worth keeping. The writing life, to me, is not about constant inspiration and ease. It is about putting your butt in the chair for thousands of hours every year, and loving it.
