In Cheryl Strayed's new memoir, Wild (Knopf, 2012), the author recounts her months-long hike along the Pacific Crest Trail, a journey that she took entirely alone after life as she'd known it had fallen apart. "It was a world I'd never been to and yet had known was there all along," she says, "one I'd staggered to in sorrow and confusion and fear and hope. A world I thought would both make me into the woman I knew I could become and turn me back into the girl I'd once been." Write about a time when you got a little wild—when you embarked upon something new and challenging, maybe something frightening, or maybe even a little dangerous. Write about the wilderness itself, but also about what brought you there, and who you had become by the time you walked back out of the woods.
