When Heaven is about to confer a great office upon you, it first exercises your mind with suffering and your sinews and bones with toil.
MenciusThe great man does not think beforehand of his words that they may be sincere, nor of his actions that they may be resolute- he simply speaks and does what is right.
MenciusThere is the work of great men and there is the work of little men. Therefore it is said, 'Some labor with their minds and some labor with their strength. Those who labor with their minds govern others; those who labor with their strength are governed by others.'1 Those who are governed by others support them; those who govern them are supported by them. This is a universal principle.
