The circle and the square
(Oct. 25, 2012) -- "Two hours later, when the salesperson brings the deal to the manager after making the client fall in love with a product that is $800 per month and the client’s budget is $400 per month the manager says, 'You idiot, you landed the client on too much product,'" said Sobel. "This principle exposes the importance of lining up the circle and square before you show a specific product to a specific client."
