Don Hamilton Jr.

“If a man has no vices, he's in great danger of making vices out of his virtues, and there's a spectacle. We've all seen them: men who were monsters of philanthropy and women who were dragons of purity. ... No, no - nurse one vice in your bosom. Give it the attention it deserves and let your virtues spring up modesly around it.”
― Thornton Wilder, The Matchmaker
