Jeez.. that guy sounds a little unpredictable. I read Bandler and Grinders Frogs into Princes and other NLP books back in the 80's. I thought I could travel the world with a skill curing people of their phobias without being weighed down by kit. I found it interesting but a little dangerous and manipulative. I left it well alone and did other stuff for money that didn't involve messing with peoples minds.
