Amy Purdy talks about the power of imagination. She explains how our lives are not determined by what happens to us, but by the choices we make. Imagination allows us to break down borders, to move beyond our circumstances, to create and constantly progress. Amy Purdy has been through hardships that most of us will never face -- or can even fathom. But what makes her story so incredible is not that fact that she lived a "normal" childhood and spent her high school years as a passionate artist and snowboarder, then traumatically lost both her legs at age 19, but how she has persevered, taking implausible challenges and rising above them. Today, Amy is an athlete; currently the top ranked adaptive female snowboarder in the world. Amy also spends a good amount of time helping others; specifically those with physical challenges get involved with snowboarding, skateboarding, wakeboarding and other action sports through the organization she co-founded Adaptive Action Sports. Challenging herself while making a positive impact on the world is a true testament to Amy's spirit. About TEDx. TEDx was created in the spirit of TED's mission, "ideas worth spreading." The program is designed to give communities, organizations and individuals the opportunity to stimulate dialogue through TED-like experiences at the local level. At TEDx events, a screening of TEDTalks videos -- or a combination of live presenters and TEDTalks videos -- sparks deep conversation and connections. TEDx events are fully planned and coordinated independently, on a community-by-community basis.
