Chuang Tzu, the Chinese Philosopher, born around 369 BC, suggests
To leave no examples of extravagance to future generations, to show no wastefulness in the use of things, to indulge in no excess of measures and institutions.
His advice is to favour living in a more just and respectful balance with nature; feel an element of solidarity to the world and people around us now as well as future generations over materialism and excess. Considering what we really need and how much of it? He is not suggesting asceticism, simply moderation and less wastefulness.
The ancient wisdom text Tao Te Ching gives us some simple and beautifully direct guidance to know better where to start.
