A great interview with Dr Robert Cialdini by Dorie Clark.
Dr Cialdini is one of the most important people regarding the subject of influence. I have reviewed his most recent book here.
Dorie Clark is one of the people I follow most online for her insights into personal branding, leadership and business. I have just read one of her books too and my review is here.
Two people I greatly admire, I really urge you watch this!
