In this video, Mark discusses the interaction between our 'primitive brain' and our 'neo- cortex', explaining how the two work together to form opinions of other people. How does Mark's explanation of this interaction between our primitive brain and neo-cortex help us to understand the following quotation from our course textbook? "Changing a buyer's attitudes and beliefs is the most difficult challenge a salesperson faces." Question #2 When Mark refers to the importance of sometimes being "inauthentic", what he's really talking about is the importance of sometimes overcoming our natural instincts or automatic behaviours, and pushing ourselves to do or say something that we ordinarily wouldn't. Think about your own personality, and about your own behavioural tendencies. Write a paragraph about a tendency or characteristic that you have that may NOT serve you well in a professional selling or business setting. Explain 1) what the tendency is, 2) how it could be to your detriment in a professional selling or business setting, 3) how you might adjust it (or act inauthentically) and 4) the positive result that you may get from making the adjustment
