The reason that nothing changes in spite of all the beautiful knowledge we are exposed to and all the rules of life that we know; is because it is not about understanding and mastering life. It is not about having knowledge; it is about becoming! We are human beings and we must become pure human beings.
It is the emotional baggage in our brains that causes all this emotionally challenged behavior including making pure man into his phony self image. The self image screws up our understanding of our self and others and how life works resulting in all this mess in society.
