If life seems to be passing you by, I highly recommend this. I was surprised at how easy and enjoyable this book was to read. The content is so substantial and I would expect such material to be too difficult to take in normally. But the author makes newer, unfamiliar concepts comfortable, and he is so funny with it. I've read most of SW's other books and seen him give talks and didn't think there was much more for him to say. So I am so surprised that this book had so much new information and ideas and is my new favourite.
