We love everything on our own account; we even follow our own taste and inclination when we prefer our friends to ourselves; and yet it is this preference alone that constitutes true and perfect friendship.
Francois de La RochefoucauldNothing is more contagious than example, and no man does any exceeding good or exceeding ill but it spawns new deeds of the same kind. The good we imitate through emulation, the ill through the malignity of our nature, which shame keeps locked up, but example sets free.
Francois de La Rochefoucauld
