Never under compulsion, out of selfishness, without forethought, without misgivings. No surplus words or unnecessary actions. Let the spirit in you represent a man. Taking up his post like a soldier and patiently awaiting his recall from life. Needing no oath or witness. Cheerfulness. Without requiring other people’s help. Or serenity supplied by others. To stand up straight, not straightened.
Marcus Aurelius, Meditations
