Part 1: Film director Ava DuVernay became the first African-American woman nominated for a Golden Globe with her Martin Luther King Jr. biopic "Selma" and later was nominated for an Academy Award for her documentary "13th," about racism entrenched in the criminal justice system. At 94 years young, legendary television creator/producer Norman Lear, best known for "All in the Family," "The Jeffersons," "Maude" and "One Day at a Time," has not allowed age to slow his work in entertainment or his involvement in the causes that he actively supports. Although gender, race, religion and 50 years separate these two extraordinary talents, they have far more in common morally, ethically and politically than many would think. What drives their creativity?
Part 2: Co-authors Nick Kristof and Sheryl WuDunn share stories of how citizens around the world inspired them, as featured in their book "A Path Appears."
