Properly practiced creativity can make one ad do the work of ten.
Advertising is the art of persuasion.
Because an appeal makes logical sense is no guarantee that it will work.
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?
Creativity is the most practical thing a businessman can employ.
Good advertising does not just circulate information. It penetrates the public mind with desires and belief.
