Always bear these facts in mind. People are hurried. The average person worth cultivating has too much to read. They skip three-fourths of the reading matter which they pay to get. They are not going to read your business talk unless you make it worth their while and let the headline show it.
Don’t think that those millions will read your ads to find out if your product interests. They will decide at a glance—by your headline or your pictures. Address the people you seek, and them only.
