For the last twenty years, Melinda Gates has been on a mission to find solutions for people with the most urgent needs, wherever they live. Throughout this journey, one thing has become increasingly clear to her: If you want to lift a society up, you need to stop keeping women down. Here, she shares lessons she’s learned from the inspiring people she’s met during her work and travels around the world. Her narrative is backed by startling data as she presents the issues that most need our attention—from child marriage to lack of access to contraceptives to gender inequity in the workplace. And, for the first time, she writes about her personal life and the road to equality in her own marriage. This is Gates' journey from a partner working behind the scenes to one of the world's foremost advocates for women, driven by the belief that no one should be excluded, all lives have equal value, and gender equity is the lever that lifts everything.
