People often underestimate the power of... Gratitude. I have chronic fatigue syndrome, and when I'm feeling bad I remind myself that even in darkness, I am the recipient of many gifts.
I felt most powerful when... I realized that though my illness left me isolated in my home, I could reach out to the world through my writing.
A true sign of power is... Forgiveness. My next book's subject is Louis Zamperini, a World War II airman. He was captured and enslaved by the Japanese and the victim of the worst atrocities, yet all he feels for this world is joy.
