I will tell you the secret of a good story. The secret is that nihilism kills movies. If you're a person that thinks fate is sealed, you will make horrible movies. The only thing needed to make a good story is recognizing that your life has meaning and that every action that you take at any moment matters.
Nihilism is at its maximum when you crave a socialist dystopia and you believe that you are the most intelligent being in the world and you consider yourself a sort of god (that kind of delusion comes when you are able to change the rules of the world without consequence). Then, fate is sealed for you and you suck at making movies
