Maria Shriver, the Peabody- and Emmy-award winning journalist, producer and best-selling author, sits down with Oprah to share inspiring quotations, prayers and reflections featured in her number one New York Times best-selling book "I've Been Thinking...: Reflections, Prayers, and Meditations for a Meaningful Life." Oprah and Maria discuss their nearly 40-year friendship and the lessons they both learned from Maria's mother, Eunice Kennedy Shriver. Maria looks back on the personal challenges she's experienced, including how she found the strength to navigate her mother's death and the grief that came afterward. Maria speaks candidly about growing up as a member of the powerful Kennedy family, and opens up about seeking her own passion and purpose beyond the legacy of her famous forebears. Maria is the founder of the Women's Alzheimer's Movement, a nonprofit committed to researching why women are disproportionately affected by Alzheimer's disease and, in so doing, finding a cure.
