You can say the right thing about a product and nobody will listen. You’ve got to say it in such a way that people will feel it in their gut. Because if they don’t feel it, nothing will happen.

You cannot sell a man who isn't listening; word of mouth is the best medium of all; and dullness won't sell your product, but neither will irrelevant brilliance.

The real giants have always been poets, men who jumped from facts into the realm of imagination and ideas.

Word of mouth is the best medium of all.

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?

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

Because an appeal makes logical sense is no guarantee that it will work.
