In fact, the Rich Roll podcast episode with James Clear is the one I'd recommend for all. Roll is a great listener and interviewer, and together they did a much better job than the book alone in focusing on the forging-an-identity part of habit formation. Highly recommended, it's something like two hours long.
There just wasn't much there to grab a hold of me. Nothing new I had not heard in multiple poscasts or read in articles elsewhere.
Not saying the book is bad, just not so phenomenal when the ideas aren't new to you.
