… noticed that I was getting a bunch of newsletter subscribers
who kept listing “my professor” as the source of how they found out about me. I finally emailed one of them and asked who their professor was so I could thank him/her. So I did.
Got an email back from the mystery professor a few hours later. Turns out it was a guy I knew from my days in cable television who continued to receive my newsletter over the years and who’s now a college professor.
You never know from which mouth the word of mouth will come from!
