While there are some worthwhile takeaways from this book, such as diverting attention away from that which stresses/drains you to what drives your passions... or recognizing and accepting your emotions yet not allowing them to rule your life... the issue I had with this book was how contrived it was. It was a call to God more than it was a focus on achieving accountability for our actions and choosing the right path toward “enlightenment.” The anecdotes were well-scripted to justify his points. Those are just a couple to start with.
So, if you pick this book up, take what you need and leave the rest. I would also consider using it as a “workbook” over a longer period of time, which is subtly implied throughout the book; however it is not marketed or presented as such explicitly.
