Before you even buy this book, I believe you need to determine what you hope to get out of it.
If you're hoping to identify with other artists who have faced doubts, fears and obstacles, you'll not be disappointed. This book delivers on its title: it is about ART & FEAR. It will describe where you are or have been. It could even help you stay there, if you choose.
This book says it explores "the way art gets made", why it often does not, and the difficulties along the way. As such, it is, in its own words "observational", not instructive. So it is not a "How To" book. It is also analytical, though not necessarily insightful, so it's not intended for your next meditation. And though other reviewers have said otherwise, I wouldn't recommend this book to help rouse anyone from their creative slumber.
If you're a practicing artist or would-be artist who is stuck, I don't believe this book will help free you. You may find identification or sympathy with other artists - maybe even justification - but not the inspiration, motivation or plain old instruction to get you going again.
Better to read something that is designed to be instructive or inspiring. (One inspiring book that springs to mind is Denise Sherkerjian's UNCOMMON GENIUS which profiles 40 winners of the MacArthur Prize. These artists cross all creative disciplines, face numerous obstacles and still create. It says a lot worth listening to and applying to the process of creating.)
I received ART & FEAR as a gift and read it as much out of curiosity as to honor the giver. I rated it 3 STARs because it (a.) has some good quotes, and (b.) helped me appreciate how differently I think about and respond to the doubt, ambiguity and chaos in my art. Compared to the Bayles & Orland landscape, I have more faith, trust and love in the process and the results of my creation.
