I cannot recommend this book highly enough. It's written from the perspective of a writer, but the advice is not unique to writing (or even to art in general, for that matter). If you're like me, you will (as the guy who wrote the intro admitted) see yourself looking back guiltily from every page. It's a quick read or listen, and if this doesn't motivate you to get off your ass and create, nothing will.
