Anna Karenina

Happy families are all alike; every unhappy family is unhappy in its own way.

There are people who, on meeting a successful rival, no matter in what, are at once disposed to turn their backs on everything good in him, and to see only what is bad. There are people, on the other hand, who desire above all to find in that lucky rival the qualities by which he has outstripped them, and seek with a throbbing ache at heart only what is good.

All the variety, all the charm, all the beauty of life is made up of light and shadow."
