I know the author personally, so consider this a biased review.
To my knowledge, this is David's first book. I was not quite sure what to expect going into it, but really enjoyed the amount of wisdom and positive energy that it provides. Anytime you feel like the world is kicking you in the teeth, just crack this open to any page and start reading.
This is not an incredibly long read, I actually read it while sitting in the car waiting for my kid to get out of practice.
I am looking forward to seeing more books from David in the future.
