Pete,
The quote below is from the New Behavior Generator on your website:
"...One guy bought the tape for one use and then put it in his dresser drawer. A few weeks later he was riding the escalator in a department store when another guy flashed a smile to two girls in front of him. They melted. He wished he could smile like that.
That evening while preparing for bed, he noticed the tape and wondered if he could use it for smiling. He tried it, and sure enough, in a couple days he was smiling nonstop.
Within a few days, his smiling "wore off" so he listened again. After several listenings over the course of a few months he found himself smiling all of the time..."
