This is one of the best book i have read in a long time. No doubt Mark H. Mccormack Created an empire with the knowledge he had of reading people and worked with them in the best way. I would say everyone must read this book at least once before managing people
I bought the book with huge expectations and the expectations was melted down the moment i looked at the content of the books. If you are in marketing business or in selling occupation the book must be proved best but for other readers who wish to find it a self help guide may glide down to zero level
