Advertising is the art of persuasion.

Never do anything yourself that you can hire someone else to do, especially if they can do it better.

Today's smartest advertising style is tomorrow's corn.

A great ad campaign will make a bad product fail faster. It will get more people to know it's bad.

In advertising, not to be different is virtually suicidal.

Just because your ad looks good is no insurance that it will get looked at. How many people do you know who are impeccably groomed... but dull?

No matter how skillful you are, you can't invent a product advantage that doesn't exist. And if you do, and it's just a gimmick, it's going to fall apart anyway.
