In vain I have looked for a single man capable of seeing his own faults and bringing the charge home against himself.
ConfuciusListen widely to remove your doubts and be careful when speaking about the rest and your mistakes will be few. See much and get rid of what is dangerous and be careful in acting on the rest and your causes for regret will be few. Speaking without fault, acting without causing regret: 'upgrading' consists in this.
