Sheryl Sandberg, the chief operating officer of Facebook and the author of Lean In, recently delivered the commencement address at the University of California at Berkley. Her address focused on what she had learned since her husband’s death a little over a year ago. She said, “I learned about the depths of sadness and the brutality of loss. But I also learned that when life sucks you under, you can kick against the bottom, break the surface, and breathe again. I learned that in the face of the void — or in the face of any challenge — you can choose joy and meaning.” She went on to say, “My New Year’s resolution this year is to write down three moments of joy before I go to bed each night. This simple practice has changed my life. Because no matter what happens each day, I go to sleep thinking of something cheerful.”
