Practically everyone arranges their life around a fairy tale of one sort or another.
Some learn it in a mosque, some in church, some in history and civics class. Yes, that includes Atheists. Just because they don't believe in God doesn't mean they don't believe in a shared mythos. Some are more helpful and practical than others but make no mistake, they are myths.
In America, many organize their lives around the myth that they are temporarily embarrassed millionaires and so consistently vote against their own interests.
