'I Know This to Be True' is a global five-year project founded on original interviews to inspire a new generation of leaders. Truth, wisdom, inspiration and what really matters for the most inspiring leaders of our time. The inimitable Ruth Bader Ginsburg, an associate justice of the US Supreme Court, embodies the power of persistence and integrity. Throughout her legal career, spanning nearly five decades, she has been an unwavering force for progress and a leading voice for equality and justice. Here, she reflects on her many years of service to the law, as well as her family life and struggle with cancer. With disarming honesty, Ginsburg discusses everything from gender equality and fitness to literature and the importance of hard work. Strong, hopeful and wise, her words stand as a guide for budding feminists and those who fight for justice around the world.
