What 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.
EpictetusHappiness and freedom begin with a clear understanding of one principle: Some things are within our control, and some things are not. It is only after you have faced up to this fundamental rule and learned to distinguish between what you can and can't control that inner tranquility and outer effectiveness become possible.
