If I had to sum it all up, I'd say there are three breeds of account executives: the play-it-safe-and-by-the-rule-book transmitting agent; the neutralist, who's never quite sure from one day to the next of his role in the agency-client relationship; and the truly creative account man, who may never write a line of copy in his life, but who, in his own wy, is every bit as creative as the finest copywriter in the business.
