[EX Q]: Good to have for those of us who cannot get the whole story. In addition, there is an interview that answers some questions. A great bonus on DVD. Thank you.
[EX A]: Good Review

[EX Q]: I just bought this book about a week ago. The first half of the book, which discusses issues such as how to implement business goals in your life, is very good. Then after that, there are various cases examples written by CEOs and others that help reinforce what they've discussed. Finally, there are several case studies with people who have become successful through their own hard work (i.e. one entrepreneur at a local store).
[EX A]: Good Review

[EX Q]: This is not what I was expecting to get. It looks very cheap, almost more for decoration than anything. However, my wife liked it, so we kept them both.
