@jwolf very good recommendation of three excellent movies, I have to admit that my favorite is "Wolf of Wallstreet", still amazes me that it is a real life story and that Jordan Belfort did what he pleased and dominated wallstreet with so much speculation. Actually this man is a lecturer who is dedicated to teaching people how to persuade and how to take advantage of these in a sale, after all the bad things he did, I think we have to admit that he knows what it is to sell. Great post!
