The Art of War by Steven Pressfield

The War of Art
by Steven Pressfield

This book was recommended on a podcast I listen to called "Back to work" with Merlin Mann and Dan Benjamin. It outlines an excellent model for how to think about the work of creating. It is a very practical approach that gives due respect to the more undefinable sources and motivations involved in making art. It's a quick read but dense with great insight. I'm also a fan of the narrator George Guidall.
