Do you believe in fate?

You know how they say that all events are related and nothing happens without a reason? I think I get it. One day you wake up and just follow a chain of thoughts, talks and steps without realizing that they are all pieces of the puzzle leading you to something incredible. And though it seems to be just a coincidence, it isn’t. Some call it fate, others quantum mechanics. But if the universe indeed leaves clues for us, do we have any sway over the outcome? Can we change the DNA of our life by taking different decisions? Or are we actually predestined to act this way because everything else is predestined as well? My favorite writer M. Kundera says (and Aslan the Lion agrees with him, heh) that we can’t possibly know what would have happened because we have only one shot at living.

I recently watched a movie called Frequences 
https://en.wikipedia.org/wiki/Frequencies_%28film%29. I know it’s three years old, but I’m kind of a cinema retard, don’t be too harsh on me. The hero is a ‘low-frequency’ guy in love with a ‘high-frequency’ girl who can’t love him back because of her impaired ability to feel.  During the film, he is looking for a way to level that difference so that they could be together. In a tight lock of events, he suddenly stumbles upon the ultimate pattern of life and gains absolute knowledge of what is and what will ever be. The point of the movie is that the script of our existence is already written and we have no choice but to play our part. No free will implied. Where is the truth? Unlike the lucky guy, I don’t know. Do you?
