Don't demand or expect that events happen as you would wish them do. Accept events as they actually happen. That way, peace is possible.
EpictetusWhat else can I do, a lame old man, but sing hymns to God? If I were a nightingale, I would do the nightingale's part; if I were a swan, I would do as a swan. But now I am a rational creature, and I ought to praise God. This is my work. I do it, nor will I desert my post, so long as I am allowed to keep it. And I ask you to join me in this same song.
EpictetusIf you would be well spoken of, learn to be well-spoken; and having learnt to be well- spoken, strive also to be well-doing; so shall you succeed in being well spoken of.
Epictetus
