Marcus Aurelius

What is divine is full of Providence. Even chance is not divorced from nature, from the inweaving and enfolding of things governed by Providence. Everything proceeds from it. (Hays translation)

Her reverence for the divine, her generosity, her inability not only to do wrong but even to conceive of doing it. And the simple way she lived—not in the least like the rich. (Hays translation)

Yes, you can--if you do everything as if it were the last thing you were doing in your life, and stop being aimless, stop letting your emotions override what your mind tells you, stop being hypocritical, self-centered, irritable. (Hays translation)

Of my grandfather Verus I have learned to be gentle and meek, and to refrain from all anger and passion... I have learned both shamefastness and manlike behaviour. Of my mother I have learned to be religious, and bountiful; and to forbear, not only to do, but to intend any evil; to content myself with a spare diet, and to fly all such excess as is incidental to great wealth.

Concentrate every minute like a Roman—like a man—on doing what's in front of you with precise and genuine seriousness, tenderly, willingly, with justice. And on freeing yourself from all other distractions. (Hays translation)
