Maybe he used NLP on himself to go from fading stage hypnotist to one of the highest paid 'entertainers' in the US.
what he actually did, was once his stage show was fading he plagiarized another hypnotists work and published his "I can make you" series...,
He then (due to having more money) successfully sued the people he plagiarized off for ....... plagiarism..
you really could not make it up...
