Luck is not without fear and trouble; Bad luck is by no means without comfort and hope. Bacon had bad luck.
Be full of hope in bad luck, and don't forget to worry in good luck, so that you can bear misfortune calmly. A collection of Horace's songs
Bad luck wanders along the same road, sometimes it comes to one person, and sometimes it comes to another. Prometheus Bound by Aeschylus
