Meditation 8.42-43
Marcus AureliusMeditationsBook 8.42
42. I do not deserve to give myself pain, for I never deliberately gave another pain.
43. One thing gives joy to one man, another to another; it is my joy if I keep my governing self intact, not turning my back on any human being nor on anything that befalls men, but seeing everything with kind eyes, welcoming and employing each occasion according to its merits.
