I want to express my appreciation for your excellent presentation at The Forum on Executive Decision Making and Influence. . . the audience was composed entirely of senior executives from major U.S. and Canadian companies. . . . The evaluations were in the ‘excellent’ range and you received more mentions as ‘The part of the program I liked most’ than any other speaker—quite an accomplishment given the competition!

This book is the de facto standard to learn the psychology of persuasion. If you don’t read it, I hope you enjoy pounding your head against the wall and throwing away marketing dollars.

No consideration of important lessons in leadership would be complete without noting Robert Cialdini’s Influence: Science and Practice.

I respect Dr. Cialdini’s work and knew he would be an interesting speaker at our conference. What I didn’t anticipate was how popular his presentation would be among the attendees. He easily filled a 750-seat auditorium, and we were turning people away at the door.

…we recently got back our reader survey results from the Oct. issue and your article was both the most read and the one that people found the most useful. Congratulations!

Bob is one of the better speakers on the subject of what persuades/influence people to use our products and services. His book should be in every sales and marketing person’s briefcase and reread frequently.
