most of this book i found to be very informative. The issues that are raised are looked at with a good perspective. However, i did find that for me there was one main problem, that was the 'revenge' bit. saying that we should copy someones bad behaviour in order to make them understand and respect us, i feel this is a childish method, and i feel that it is sinking to a lower level, this point is also argued in the book, but i do feel that there is still a better way to do things. Otherwise, on the whole the book is good, its useful and has a good many techniques that would be advantageous to anyone.
