David M. Ogilvy

The best ideas come as jokes. Make your thinking as funny as possible.

A good advertisement is one which sells the product without drawing attention to itself.

Never 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.

Political advertising ought to be stopped. It's the only really dishonest kind of advertising that's left.

In the modern world of business, it is useless to be a creative original thinker unless you can also sell what you create. Management cannot be expected to recognize a good idea unless it is presented to them by a good salesman.
