First of all, I want to state that fortune telling or clairvoyance is a very rare talent which very few tellers are gifted with. So as popular as the act is, very few tellers can actual look into the future. So, as tempting as it is for me to want to see into my future, I really doubt i'll want to indulge. Most people end up getting conned in the process. This was called a confidence trick in the past. Going back to the question, I like to think that looking into the future to see what's to come is not a good idea for me. What happened to expectations. Knowing the future only kills the zeal to work towards a certain goal. In some ways, this might mean that looking into the future may have negative effects like changing that very future. Let's look at an instance below. A hard working man who decides to look into his future. He does and the teller says she sees him rich. Now, she doesn't tell him how he gets rich or when, but just that he gets rich. A lot of people upon getting such information might take life and their ongoing work not too serious. After all, they still will get rich. This young man does the same and becomes very lazy. Neglecting to work harder and missing opportunities, not knowing his work is actually his get rich means. What do you think will happen to the future of this young man if he continues lazzying around thinking he'll get rich anyways? Does it seem like his future is going to be different from what the foutune teller saw? This is what I mean when I say looking into the future can very well change that future for the said person.
