A few days ago, I suggested that you might want to consider public speaking as a way to gain customers, clients or subscribers if your business is a local one.
In keeping with my continuing feature of providing downloads of “good old books” that are still relevant today, I have a fine candidate related to public speaking: “The Art of Public Speaking,” by J. Berg Esenwein and Dale Carnegie. He spelled his name Carnagey at the time, but it’s the same Dale Carnegie that later wrote about winning friends and influencing people.
“The Art of Public Speaking,” originally was sold as a correspondence course. And it actually provides good ideas and training that is still used for preparing speakers.
