Sandberg's speech on resilience may form basis for second book

San Francisco

JUST over a year since the death of her husband, Facebook Inc chief operating officer Sheryl Sandberg has learned how to be more resilient - a hard-won skill she's sharing first in a graduation speech and potentially in a second book.

Ms Sandberg told graduating students at the University of California at Berkeley on Saturday that their lives may someday be clouded by tragedy or a challenge they can't yet imagine. What will define them is how they gather the strength to overcome it, and find gratitude and appreciation in life.
