Literature Reference: 君子素其位而行，不愿乎其外。素富贵，行乎富贵；素贫贱，行乎贫贱；素夷狄，行乎夷狄；素患难，行乎患难。君子无入而不自得焉。——《中庸》 The superior man acts according to his position and does not desire what is beyond it. In wealth and honor, he acts as one should in wealth and honor; in poverty and obscurity, he acts as one should in poverty and obscurity; among barbarians, he acts as one should among barbarians; in distress, he acts as one should in distress. The superior man finds himself at ease in every situation. Source from 'The Doctrine of the Mean'.
