Boundaries define us. They define what is me and what is not me. A boundary shows me where I end and someone else begins, leading me to a sense of ownership.
Success is doing what you want to do, when you want, where you want, with whom you want, as much as you want.
牛马生着四足,这是天性;给马戴上笼头,给牛穿上鼻绳,就是人为。所以说,不要人为毁灭天性,不要用故意造作去毁灭天命,不要以德行去为名利殉葬,谨守天道勿使丧失,这就叫返归本真。
