I was introduced to this book and these principles by a college who is a Dale Carnegie coach. We have already used the format to frame a discussion document to a potential client. It enabled us to be clear in our thinking and subsequently to demonstrate our understanding of our client's problems. Highly recommend it.
I downloaded this for my wife and gained great brownie points. Buble' is at his finest when he sings in the 'American Song Book' style. His voice is a musical instrument, silky smooth and richly toned. I really like it.
