Sheryl Sandberg Instagram – Today, we celebrate Dr. Martin Luther King Jr. Dr. King was relentless in his pursuit of justice, equality, and peace for all people of every race, religion, and nationality. He called on us to confront hatred and ignorance, giving way to tolerance and love. And he taught us to reach across barriers of understanding — especially when it is hard. Dr. King believed that our words and actions have the power to shape a better future. In all we say and do, we should strive to live up to his example.
