In the modern world of business, it is useless to be a creative, original thinker unless you can also sell what you create. - David Ogilvy

When I write an advertisement, I don’t want you to tell me that you find it "creative". I want you to find it so interesting that you buy the product. When Aeschines spoke, they said, "How well he speaks". When Demosthenes spoke, they said, "Let us march against Philip."

The creative process requires more than reason. Most original thinking isn't even verbal. It requires 'a groping experimentation with ideas, governed by intuitive hunches and inspired by the unconscious.' The majority of business men are incapable of original thinking because they are unable to escape from the tyranny of reason. Their imaginations are blocked.

Almost any question can be answered, cheaply, quickly and finally, by a test campaign. And that’s the way to answer them – not by arguments around the table.
