Properly practiced creativity can make one ad do the work of ten.

Today's smartest advertising style is tomorrow's corn.

You cannot sell a man who isn't listening; word of mouth is the best medium of all; and dullness won't sell your product, but neither will irrelevant brilliance.

Those who are going to be in business tomorrow are those who understand that the future, as always, belongs to the brave.

No matter how skillful you are, you can't invent a product advantage that doesn't exist. And if you do, and it's just a gimmick, it's going to fall apart anyway.

Just because your ad looks good is no insurance that it will get looked at. How many people do you know who are impeccably groomed... but dull?

Advertising doesn't create a product advantage. It can only convey it.
