Why people go on struggling is because they logically make some things work in their life. Because it worked well, they try to extend this logic to every aspect of their life, and they just mess themselves up completely. Somebody else operates some other part of life illogically and it works well. They try to extend this to all aspects of life, and again it becomes a mess. They do not understand that the physical needs logic. For that which is beyond the physical, logic is useless.
