While in the background but with examples referring to figures from another age

This book is clear by his effective content. It reminds of the essential and indispensable communication principles (which we sometimes forget in the heat of the action).
This is a good book for those who want to review their communication, and possibly advance.
The note of "3/5" is that the examples are references to American personalities forgotten or ignored for most (with exceptions) serve the remaining examples on the very bottom right.
Failing a best book yet => it is still a book to read I think.
