Advertising is the art of persuasion.
In advertising, not to be different is virtually suicidal.
Properly practiced creativity can make one ad do the work of ten.
Today's smartest advertising style is tomorrow's corn.
There is no such thing as a good or bad ad in isolation. What is good at one moment is bad at another. Research can trap you into the past.
Adapt your techniques to an idea, not an idea to your techniques.
