A chronic lack of pleasure, of any enjoyable, rewarding or stimulating experiences, produces a slow, gradual, day-by-day erosion of man's emotional vitality, which he may ignore or repress, but which is recorded by the relentless computer of his subconscious mechanism that registers an ebbing flow, then a trickle, then a few last drops of fuel--until the day when his inner motor stops and he wonders desperately why he has no desire to go on, unable to find any definable cause of his hopeless, chronic sense of exhaustion.
Ayn RandIn all proper relationships there is no sacrifice of anyone to anyone. An architect needs clients, but he does not subordinate his work to their wishes. They need him, but they do not order a house just to give him commission. Men exchange their work by free, mutual consent to mutual advantage when their personal interests agree and they both desire the exchange.
Ayn RandValue is that which one acts to gain and/or keep. Virtue is the act by which one aims and/or keeps it.
