In anycase, the way that creating your own reality can be good is the way that we live in a society where social relations have become more and more of the determiners of existence. Think about money, the single object dominates our lives. Money has been called an illusion because it's existence depends on our collective belief. But that's no a good word. Illusion only makes sense when I can close eyes and it just disappears.
Money is social relation.
I don't know if you've ever seen a tensile structure. They have the configuration of poles and string, where the poles are tied together and none of the poles touching. The thing is held-up even though you think it fall down. Money is held up by the way we are ridiculously tied together. Anyway the larger point to all of this is that the more modern society progresses, the more we are held together by our present collective activity.
