Hard work never killed a man. Men die of boredom, psychological conflict, and disease. They do not die of hard work.
David OgilvyNever write an advertisement which you wouldn't want your family to read. You wouldn't tell lies to your own wife. Don't tell them to mine.
David OgilvyWhy do eight out of ten new consumer products fail? Sometimes because they are too new. The first cold cereals were rejected by consumers. More often new products fail because they are not new enough.
David OgilvyBig ideas come from the unconscious. This is true in art, in science, and in advertising. But your unconscious has to be well informed, or your idea will be irrelevant. Stuff your conscious mind with information, then unhook your rational thought process. You can help this process by going for a long walk, or taking a hot bath, or drinking half a pint of claret. Suddenly, if the telephone line from your unconscious is open, a big idea wells up within you.
