Displaying incredible perseverance, Mary Lou Retton overcame injury and etched her name into the annals of history in 1984 as the first U.S. Olympic gymnast to win individual all-around gold. Retton’s feat — accomplished on home soil at the Los Angeles Summer Games — won the heart of a nation and even earned her a coveted spot on Wheaties cereal boxes. In her post-athletic career, she pivoted toward sharing the philosophies behind her success, including the power of positivity. Maintaining a can-do attitude is contagious, and will attract opportunity, joy, and the kind of people who can boost us up.
