Failure to read what is happening in another's soul is not easily seen as a cause of unhappiness: but those who fail to attend the motions of their own soul are necessarily unhappy.
Marcus AureliusIf someone is able to show me that what I think or do is not right, I will happily change, for I seek the truth, by which no one ever was truly harmed. Harmed is the person who continues in his self-deception and ignorance.
Marcus Aurelius
