In The Confidence Code, Claire Shipman and Katty Kay completely undress the concept of confidence. Is it selfworth or self-esteem? Is it real or imagined? They endeavor to understand how widespread the lack of it is and how this impacts the larger subject of leadership and success. They dig into the critical question of growing up female: where confidence comes from and why it feels so ephemeral. By examining cutting-edge research, sharing their own and other notable women's stories and providing practical principles, Kay and Shipman do more than merely admonish women to "lean in" to their careers. Rather, they give them the inspiration and the tools to close the gap between insecurity and fulfillment.
