Like acting, sales works best when hidden. This explains why almost everyone whose job involves

 distribution—whether they’re in sales, marketing, or advertising—has a job title that has nothing to

 do with those things. People who sell advertising are called “account executives.” People who sell

 customers work in “business development.” People who sell companies are “investment bankers.”

 And people who sell themselves are called “politicians.” There’s a reason for these redescriptions:

 none of us wants to be reminded when we’re being sold.
