I listened to the audio book version of this and recommend it. It's obvious this material is very meaningful to Peterson, as multiple times his voice, such a unique blend of Canadian politeness and nothing-held back motivation, quavers through difficult passages. The effect is profound. The "12 Rules" seem somewhat arbitrary, little more than a framework for attaching Peterson's meandering tangents, compelling anecdotes, and at times challenging perspective, but still the overall package is an excellent provoker of thought and inspiration.
