Scatter, clutter, weight

The opposite of simplicity, as I understand it is not complexity, but scatter, clutter, weight.  Returning from a journey ... I yearn to pare my life down to essentials.  I vow to live more simply, by purchasing nothing that I do not really need, by giving away everything that is excess, by refusing all chores that do not arise from my central concerns.  I make room for silence.  I avoid television with its blaring novelties, and advertising, with its phony bait.  Whenever possible, I go about town on bicycle or on foot.  I resolve to slow down and savor each moment instead of always rushing on into the future.

Simplicity

Voluntary simplicity [is] a manner of living that is outwardly more simple and inwardly more rich, a way of being in which our most authentic and alive self is brought into direct and conscious contact with living.  This way of life is not a static condition to be achieved, but an ever-changing balance that must be continuously and consciously made real.  Simplicity in this sense is not simple.
