“I had the pleasure of seeing David Thiel present his workshop “The Marketing Minded Mentalist” at MindVention. I was also privy to getting one of the very first copies of his book. Let me just say this – If I had this material 40 years ago I would have made many thousands of dollars! Everything David states in the book is right on. If you get this material, and apply it, you WILL succeed. There is nothing else I can say!”
