If you love men and they are unfriendly, look into your love; if you rule men and they are unruly, look into your wisdom; if you are courteous to them and they do not respond, look into your courtesy. If what you do is vain, always seek within.
The 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.
