The rules your parents teach you to live by are very different than the rules the world actually runs by. Most of the conventional wisdom is not only wrong, it’s a lie told to us by people who want to control us. It doesn’t help us, it helps them. Pretty much everything we’re told as children by the established power structures in our lives are made up fairytales used to reinforce that control: Santa Claus, the Easter Bunny, the Tooth Fairy, fat-free frozen dinners, religion, and metering lights on the highway - the list goes on.
Here’s the thing: learning that the world is not what you were taught is usually just part of becoming an adult. The people who blindly follow the rules are getting fucked, and the people who don’t can get away with theft and murder. At some point we all figure this out. Sometimes it’s explicit, other times it’s just a feeling in our gut.
