It is weak and silly to say you cannot bear what it is your fate to be required to bear. 

Luck takes the step that no one sees.

Survivors look back and see omens, messages they missed.

Good or ill fortune is very little at our disposal.

We do not suffer by accident. 

Good fortune is light as a feather, but nobody knows how to hold it up. Misfortune is heavy as the earth, but nobody knows how to stay out of its way.

Nothing is as obnoxious as other people’s luck.

Some folks want their luck buttered.

It is so difficult not to become vain about one’s own good luck.

Luck is not something you can mention in the presence of self-made men.

Casting lots causes contentions to cease, and keeps the mighty apart.

Luck, in the great game of war, is undoubtedly lord of all.

Good fortune turns aside destruction by a great god.
