Every year, my father creates a Christmas treasure hunt to lead us to our big family gift. This treasure hunt drew clues from gems he collected from friends and family: a letter my brother wrote at seven about that day's fishing trip; one of my blog entries; my grandfather's account of how he joined the Air Force during WWII; an uncle's essay about how he ended up in law school by accident; and a fellow doctor's published account of how he restored vision to a man twenty years blind. Every writer had preserved a precious memory, an event that would have otherwise been lost.
My father's point: we are surrounded by heroes, but we only know it by the accounts we share with each other. So write!
