A lot of today's campaigns are based on optimum positioning but are totally ineffective - because they are dull, or badly constructed, or ineptly written. If nobody reads your advertisement or looks at your commercial, it doesn't do you much good to have the right positioning.
David OgilvyFirst, make yourself a reputation for being a creative genius. Second, surround yourself with partners who are better than you are. Third, leave them to go get on with it.
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.
