Self-fulfilling Prophecy

Do you know this? You are totaly sure that something will end up in a bad way, and in the end it does? Why do we still try things when we are sure that this will never work?
It is hard to fail over and over again. It arises the question how often we have to do the same mistakes until we know that it is a mistake.
But we still have to look forward, maybe the future will brings something better.
So by doing mistakes we sometimes learn something about ourself. Like Thomas Edison said: I have not failes i just found 1000 ways that did not work. :-)
So lets keep trying, maybe one day we find the right way.
