Sheryl Sandberg is synonymous with Facebook, and Silicon Valley success, and she’s the voice of “Lean In.” She joins us, frank and vulnerable, together with the psychologist Adam Grant. His friendship — and his research on resilience — helped her survive the shocking death of her husband while on vacation. They share what they’ve learned about planting deep resilience in ourselves and our children, and even reclaiming joy. There is so much learning here, on facing the unimaginable when it arrives in our lives and being more practically caring towards the losses woven into lives all around us.
