It takes a big idea to attract the attention of consumers and get them to buy your product. Unless your advertising contains a big idea, it will pass like a ship in the night. I doubt if more than one campaign in a hundred contains a big idea.
David OgilvyGood copy can't be written with tongue in cheek, written just for a living. You've got to believe in the product.
David OgilvyNever write an advertisement which you wouldn't want your own family to read. You wouldn't tell lies to your own wife. Don't tell them to mine. Do as you would be done by.
