Always the last pick for team sports because of his small stature, David McGillivray drove himself to excel at individual sports. When he was 16, he set himself up for the one "failure" that would motivate the rest of his life. He attempted to run in his first Boston Marathon - without training for the event. Not crossing the finish line could have been a crushing blow. Instead, he went on to complete 115 marathons and eventually to become the Boston Marathon's race director. At age 23, McGillivray completed his celebrated 3,452-mile run across the United States to raise money for cancer research. The story of his journey and what he learned about himself will give all readers a new understanding of how to prepare for and achieve success. McGillivray's many accomplishments will convince readers that virtually any goal is possible. This book will motivate them to overcome the mental obstacles that often keep dreams from becoming reality.
