All Things are Accomplished

One of my favorite lines from the Tao Te Ching highlights the comparison between Nature or the Tao and the human experience. How often do I rush about trying to accomplish everything I set out for myself only to feel disappointment, frustration, and even anger when I don't? What do I feel is so necessary to achieve -- only myself, in this lifetime -- when I am a part of a continuous oneness that accomplishes all things within an infinite and unknowable arc of time?
