Not bricht Eisen. Necessity is the mother of invention. Ohne Fleiss kein Preis. Never hurt an animal just for fun, just think if to you'twere done. Reden ist Silber, Schweigen ist Gold.
Silence is golden, speech is silver.
Shoemaker stick to your last. Weissbrot macht Leute tot. Dark bread makes cheeks red, white bread makes people dead. Sicher ist sicher. Don't rock the boat.
