"Happiness is dependent not on producing as much as possible but on producing as little as possible. Comfort and understanding are dependent upon producing only so much as is compatible with the enjoyment of the superior life. Producing more than this involves a waste of mankind’s most precious possessions. It involves a waste of the only two things which man should really conserve - the two things which he should use with real intelligence and only for what really conduces to his comfort. When he destroys these two things, he has destroyed what is for all practical purposes irreplaceable. These two things are the natural resources of the earth and the time which he has to spend in the enjoyment of them."
