Interesting read, but it seems that he has defined the classic sales person as extrovert and the analyst as introvert. And of course he pounds the table that introverts are smarter but extroverts make all the money.
I truly admire the "salesperson" (including many politicians) who can go out there and play the game but I am not sure that is the only extrovert personality. I think there are extrovert personalities that do require downtime and also have disdain for the masses. Just because one is an extrovert, doesn't mean you love people. And there are introverts that are the shy, reclusive types, with not great social skills.
Black, white and shades of grey.
