The predefined beliefs we grow up with are just bloatware in our system. Just like in Computer Systems, some of them are easy to uninstall while others are not very straight-forward (uninstalling Instagram vs uninstalling Edge), but they sure are removable. It's a matter of effort. If we continue with the same beliefs as everyone else, then we will be yet another replica of "everyone else".
"If you change nothing, nothing changes." This is something to remember.
