Calmly do your duty

German saying

Don't listen to what people say
Calmly do your duty
God will not be asking them
when he judges you that day.

—Anonymous; possibly by Eva von Tiele-Winckler (1866–1930)

Höre nicht was Menschen sagen
Tue ruhig deine Pflicht
Gott wird nicht die Menschen fragen
Wenn Er dir dein Urteil spricht
