Reading fortune for people

I know that lots of people says that fortune telling or whatever relate to it is kind of superstitious to believe in it. I am not 100% believer of it too. But I am curious about it. So when i get to know people who knows some skills on it, I will ask. When I just get to learn some skills on it, I will try on people and see if the method works. When I am working I try it on friends and some people which I just get to know. I am quite surprise that it is about 70% to 80% accuracy. As that method is taking lots of time to do and need DOB and time. So now I seldom use. I try on other methods. To my surprise, even in cards it is quite accurate.
