You could say a lot has been said about advertising. I have spent over half a century involved as a provider and a recipient of the  path created to stimulate action on Wants and Needs”. There isn’t a simpler way to describe why anyone buys anything and those are the only two reasons. You can spend a lot of time discussing it, dissecting it, pondering and arguing it but in the end it will boil down to those two factors. Advertising has always been linked to art “a picture is worth a thousand words” however my experience has proven that even the best artistry is lost on the wrong message. Identifying the message is the first step in a successful advertising experience.  Then put that message together with Art that works not Works of Art and leave the rest to the marketplace!
