Book excerpt: What's Within You Is Stronger Than What's In Your Way No one believes this more than David Shurna and Tom Lillig, co-founders of No Barriers USA. In 2003, they launched this award-winning nonprofit with the mission to help people reach their fullest potential, no matter the obstacles they face. Now, in What's Within You, they use the proven No Barriers framework to teach you step-by-step how to break through your own challenges and live a driven, purposeful life. This narrative guide will introduce you to world-famous barrier breakers like fellow co-founder Erik Weihenmayer, the first blind person to summit Mt. Everest, and Mandy Harvey, the deaf jazz vocalist whose America's Got Talent performances captured the hearts of half a billion people. Despite the barriers-both big and small-that each of us face, we can learn how to push past them, reconnect with our purpose, and unleash the best in ourselves and others.
