Fortune tellers tells you a general situation, general advice and general happenings.  So in general, the advice is too broad that even them are confused on what to specifically say to you  .  Same goes with atrology (stars reading) and with million of people who is under that sign, there is no surprise that one of them have that thing happen.

I always believe that luck comes to those who prepared, have knowledge and strategy to minimize any risk factor.  And luck never come to those who do nothing.  So luck is something that we create and been rewarded.  Anything that happen without any effort is called chance, it is packaged in the event.
