The biggest problem which besets almost every agency is the problem of producing good campaigns. Copywriters, art directors, and television producers are easily come by, but the number of men who can preside over an agency's entire creative output - perhaps a hundred new campaigns every year - can be numbered on the fingers of one hand. These rare trumpeter swans must be capable of inspiring a motley crew of writers and artists; they must be sure-footed judges of campaigns for a wide range of different products; they must be good presenters; and they must have a colossal appetite for midnight oil.
