I'm 23 and I just finished a Business and Communications degree, but this book taught me so much more about effective communication than anything else. So much of the book seems really obvious but no one really uses the techniques. After reading it I have noticed so many people violating the rules in the book and then wondering why they aren't getting results. It really shows you what you are doing wrong in your everyday interactions and the ideas stick so you remember what you should be doing when the situation arises. There was a noticeable difference almost straight away.
