When you are annoyed at someone's mistake, immediately look at yourself and reflect how you also fail; for example, in thinking that good equals money, or pleasure, or a bit of fame. By being mindful of this you'll quickly forget your anger, especially if you realize that the person was under stress, and could do little else. And, if you can, find a way to alleviate that stress.
Marcus AureliusWhen men hate or blame you, or say hurtful things about you, look deeply into their hearts and see what kind of men they are. You'll see how unnecessary it is to strain after their good opinion. Yet you must still think kindly of them. they are your neighbors. The gods help them as they do you, by dreams and oracles, to win their hearts' desires.
Marcus AureliusIn one way an arrow moves, in another way the mind. The mind indeed, both when it exercises caution and when it is employed about inquiry, moves straight onward not the less, and to its object.
Marcus AureliusOur inward power, when it obeys nature, reacts to events by accommodating itself to what it faces - to what is possible. It needs no specific material. It pursues its own aims as circumstances allow; it turns obstacles into fuel. As a fire overwhelms what would have quenched a lamp. What's thrown on top of the conflagration is absorbed, consumed by it - and makes it burn still higher.
