The world is not an open place. most people are living scared. most people don't know if whatever small or big decisions they are making are right or wrong. most people don't even have a reference to judge something being right or wrong. most people are just following social norms. social norms are most people's safety net. the moment they go out of it they are frawn upon by everyone, even by their own parents. parents like anyone else has to conform with the social values. that's where everyone extract value to their life. people feel valuable when other people think good of them becuase they are good at following norms laid out by our elders which now are hidden forces silently directing our lives to that path which is safe for everyone to follow. 
but if someone decides to question the social norms. people would be quick to question his sanity. even such a person would themselves question their sanity.
