'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. Revolutionary anti-apartheid leader Nelson Mandela devoted his life to ensuring liberation, equality and justice for the people of South Africa. Incarcerated for twenty-seven years, his endurance and faith in a justice to come remain an inspiration to all. Here, two of his former colleagues, Sello Hatang and Verne Harris, share little-known stories from his life as they explore the qualities and disciplines that enabled him to lead a country through seemingly insurmountable challenges. With excerpts from Mandela's own reflections, this book is a moving reminder of his legacy and encourages every reader to find and nurture the leader within.
