You may be always victorious if you will never enter into any contest where the issue does not wholly depend upon yourself.
EpictetusNo man is free who is not master of himself... Is freedom anything else than the power of living as we choose?
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.
