Today we have a bonus episode of the podcast with a very special guest. Many of the writers we speak with on the podcast are people who have made their names in the worlds of fiction, journalism or memoir, but today we're speaking with a writer who was working on changing the world long before she started thinking in terms of books. Philanthropist, businesswoman and global advocate for women and girls, Melinda Gates is the co-chair of the Bill & Melinda Gates foundation and the founder of Pivotal Ventures, a company working to drive social progress for women in the United States. She joined us on the phone to talk about her new book The Moment of Lift: How Empowering Women Changes the World. It combines a memoir of Gates's work to address the challenges that face ordinary women around the globe and an audacious analysis of how a change in the way we think about advocacy and women's rights can unlock startling possibility for change. She spoke to us on the phone from her office in Seattle just before The Moment of Lift was published.
