Fairy tales do not tell children that dragons exist. Children already know this. Fairy tales tell children the dragon can be killed.
G. K. Chesterton
You never change things by fighting the existing reality. To change something, build a new model that makes the existing model obsolete.
Buckminster Fuller
There can be only one permanent revolution — a moral one; the regeneration of the inner man. How is this revolution to take place? Nobody knows, but every man feels it clearly in himself. And yet in our world everybody thinks of changing humanity, and nobody thinks of changing himself.
Leo Tolstoy
