" All willing springs from lack, from deficiency, and thus from suffering. Fulfillment brings this to an end; yet for one wish that is fulfilled there remain at least ten that are denied. Further, desiring lasts a long time, demands and requests go on to infinity, fulfillment is short and meted out sparingly. But even the final satisfaction itself is only apparent; the wish fulfilled at once makes way for a new one; the former is a known delusion, the latter not as yet known. No attained object of willing can give satisfaction that lasts and no longer declines…Therefore, so long as our consciousness is filled by our will, so long as we are given up to the throng of desires with its constant hopes and fears, so long as we are the subject of willing, we never obtain lasting happiness or peace… "

― Arthur Schopenhauer , The World as Will and Representation, Vol. 1
