To simplify our lifestyle is to make use of fewer resources in our daily living. Living simply is good for all and good for the earth, but especially for self.
Living simply will require a change in values and priorities. Living simply is not just for individuals, but for whole communities, cities, countries.
Living simply does not mean that we live like the poor, but that we are mindful of the poor. As the saying goes, "live simply, so that others may simply live."
