"Temptations, of course, cannot be avoided. But because we cannot keep birds from flying over our heads, there is no need that we should let them build a nest in our hair." -- Martin Luther's Large Catechism, "Explanation of the Sixth Petition" ("Lead us not into temptation.")
"That the birds of worry and care fly over your head, this you cannot change. But that they build nests in your hair, this you can prevent." --Chinese proverb
