Resilience is not an innate trait but a learnable skill. Through examples from Sandberg's life and others who faced severe losses and challenges, they demonstrate that we can learn to cope with crises and emerge stronger.

No one needs to face adversity alone. Sandberg emphasizes the importance of a supporting network of family, friends, and colleagues, encouraging open discussion about grief and loss and accepting help rather than trying to manage everything alone.

While the pain of loss never completely disappears, we can learn to find joy and meaning in life again. Sandberg and Grant show how we can change our perspective and focus on things that give us strength and hope.
