If thou workest at that which is before thee ... expecting nothing, fearing nothing, but satisfied with thy present activity according to Nature, and with heroic truth in every word and sound which thou utterest, thou wilt live happy. And there is no man who is able to prevent this.
Marcus AureliusWhen force of circumstance upsets your equanimity lose no time in recovering your self-control, and do not remain out of tune longer than you can help. Habitual recurrence to the harmony will increase your mastery of it.
Marcus AureliusIn man's life, time is but a moment; being, a flux; sense is dim; the material frame corruptible; soul, an eddy of breath; fortune a thing inscrutable, and fame precarious.
Marcus Aurelius
