A person can only pursue simplicity for a short time before he either becomes disillusioned or else discovers some greater purpose to his simplifying effort. For simplicity itself is not an end goal. Our lives are not designed to be empty of all things, material or otherwise. We must be filled with the right things. If by pursuing simplicity we empty out the material excess but add no greater purpose in its place, we will only make room for some new mess in our lives.
