My mom went to see an astrologer (fortune teller) today and was telling us about it afterwards. The guy foretold about our future – jobs, family life, impending bad times, following good times and stuff. He also had prescribed remedial measures to be taken to avert the bad luck that's going to befall me between October 2014 and March 2017. Remedial measures mostly included visiting temples, praying to particular deities etc. Then I thought of Voldemort. He would  still have been ruling the world if he hadn't bothered about the prophecy and tried to act upon it. What other people think or say will never have any impact on you, unless you do anything about it.
