Overall, I quite liked this book. I've always had a good feeling about Willie Nelson, and this book showed me a lot of what makes him tick in ways that reinforce that good feeling. I picked it up as a break from some heavier reading, and I'm glad I did; it was refreshing. (The other reading isn't heavy in a bad way; it just requires a lot of cognitive work.)
There are a few moments -- mostly at the end -- where Willie and Turk insert some of what must be Willie's pet notions in a way that feels slightly pushy and out of place, but with a bit of toning down, including not devoting a whole chapter (each) to a couple of them, they could have been smoothly rolled into the whole thing in a much more natural way that would feel better and perhaps reach more people with their positive intentions. Ignoring those missteps, though, it is a great journey through some (perhaps a bit romanticized) history and attitudes of Willie Nelson's, with a surprising depth of understanding and wisdom, even if not rivalling the greatest examples of understanding and wisdom I've found in other texts over the years.
It's broken up into easily digested, natural pieces for most of the book. It's very easy reading, with a welcoming tone and generous sprinklings of levity. It does a lot to demonstrate where common illusions of extremes can be brought together to show people have more in common with each other than they may think. A few moments of obviously not-well-examined conventionality show through to mar the smoothness, but they're pretty mild and, given dominant culture, understandable.
I enjoyed the book a lot, and I think a lot of other people could as well. It also prompted me to take some notes, which is a very good sign for a light-hearted book like this.
