In the book Psychic Mafia, M. Lamar Keene exposes the secrets of what it's like to work as a paid psychic. Keene points out that many people think they have psychic powers, and give readings to friends and family for fun. Those who go on to start a business, though, eventually must come to the realization that they are doing nothing more than magic tricks like cold reading (the practice of making general statements and allowing your mark to fill in details and guide the conversation). Keene explains that eventually, all professional psychics must make a decision – to continue to give readings, knowing they are frauds, or to drop out. He chose the latter.
