It's really easy to feel like a failure in those cases. And when one gets into one of those periods, it can be hard to get over it - "oh, I won't bother, I'm producing nothing but crap anyway." I know I've had times like that, and I'm sure a lot of other people on this site have had 'em too.

There's an interesting book I've recently read called "Art and Fear: Observations on the Perils (and Rewards) of Artmaking" (ISBN 0961454733) that talks about this. At least one of the authors, if not both, is a photographer.
