Science of Influence Volumes 1-12: Strategies & Syntax of Persuasion (Twelve CDs plus GIANT Manual on CD)
This is the place for you to begin. BUT, this is by no means a basic course in influence. Including recent research, this 13-hour program has all the latest strategies and sequencing information for influencing others. It's unlikely you have heard or read any more than perhaps 15% of the material covered in this home study program and yet without this material it's almost impossible to predictably influence others.
