Why do people love video games? It’s a predictable reward. You take X action, and you get Y result. Even if the game is meant to be random, there is always a form of logic.
However, the real world does not have this logic. Of course, there are social norms, but it isn’t always clear what works and what doesn’t work – this lack of logic goes even further when one considers that every individual is literally a universe onto him or her self.
So, if you want to get to a level of peace in life, you have to accept the fundamental insecurity of the universe. In fact, you have to embrace insecurity and look into the abyss until it looks back.
