Ruth Bader Ginsburg, via The New York Times:
Another often-asked question when I speak in public: “Do you have some good advice you might share with us?” Yes, I do. It comes from my savvy mother-in-law, advice she gave me on my wedding day. “In every good marriage,” she counseled, “it helps sometimes to be a little deaf.” I have followed that advice assiduously, and not only at home through 56 years of a marital partnership nonpareil. I have employed it as well in every workplace, including the Supreme Court. When a thoughtless or unkind word is spoken, best tune out. Reacting in anger or annoyance will not advance one’s ability to persuade.
