Why can fortune tellers make others feel a little magical … really?

The purpose of fortune telling is not only to let you "know your life", but more importantly, to let you "change your life". The simplest example: a real fortune teller will teach you how to change the sentence "rob them, they are better at reading your true thoughts, and then tell you some jargon. If you don't understand, you will feel, ah, this master is not bad, and then sometimes looking for a fortune teller is like burning money with the dead, in order to feel at ease." They may say that they know what they are doing. If we are lucky, why do we have to tell fortune? They're all here anyway, don't you think?
