"The takeaway from this experience is simply how awesome God can allow our time on this planet to be."
Disregarding the argument of whether God is real or not, the fact that believing in an entity can give you a physical output is something worth acknowledging.
That being said, at some points, it is hard to overlook the religious influence this book has, and for a non-Christian, I could see it being incredibly repetitive. To that, I say that Ed wrote this book firstly for him, and you are a secondary along on his ride.
If you reduce the car aspect out of this book (which we all love), this book asks the question of what that "thing" in your life is, and secondly, if you are willing to chase it. If you have to ask the second part, its not your "thing."
Its nice hearing someone who believes in the same things doing things that you like doing.
