In writing advertising it must always be kept in mind that the customer often knows more about the goods than the advertising writers because they have had experience in buying them.
John WanamakerIf we could only make our hands move as actively as our tongues, what wonders we could accomplish! Almost everyone loves to hear his own voice. It is so easy, too! Yet if we could say less and do more for each other's good, not alone would every home be happier, but communities would be enriched thereby. Instead of criticism by speech, to show someone a better way to do a thing would be of much greater value.
