I found that the sale (placement) of books and magazines was always a challenge, but it was still attainable.
When the magazines switched from semi-monthly to monthly, magazine calls were automatically cut in half. Return visits that were made "just to say Hi" were hugely awkward.
I never participated in the "please watch a video on my tablet" work, but I would imagine that the fail rate compared to magazine placement is massive.
Reducing magazine frequency yet again would make me worked up inside. Return visits will virtually disappear altogether.
Would anyone want to do door-to-door in the future?
