Review title: Complete waste of time...
Product review: The author is so very opinionated about politics that reading it is difficult. In addition the entire book is mostly on how to be a good listener, what to listen for, etc. Only the last few chapters have any reference to how to persuade people and it's very unremarkable information. Suggested my university drop this book from their line-up.
