I am one of those guys who in a face-to-face situation could'nt persuade anyone :), but online i influence hundreds of thousands of people everyday to do what i want them to do!. So its no wonder, i am very much into behavioral psychology!, i love books like Tipping Point & Freakonomics...Currently i am reading a book Psychology of Persuasion .This book explains some great psychology sales tricks, really interesting stuff!
