Transcript for Melinda Gates on how women can empower other women
Gates. For many 0 years she has made it her mission. Now she's out with a new book called "The moment of lift" offering a rare look inside her life, the women, the girls all over the world who have helped make her the powerful mother, wife and working woman she is today. Please welcome Melinda Gates back to "Gma." I thoroughly enjoyed the book. It's thought provoking. What made you want to write this book now? Because equality can't wait. I feel like we have this moment in time. This window is open. Yeah. This window is open because of the me too movement, the number of women who have come into congress but yet if we don't use this window of time, we won't really get equality. And even at the current rate we're getting women into congress which looks promising it will still take us 60 years to reach equality in congress. 60 years and that's too long. No, it is. You back up -- you back everything up with data and talk to real people and get everything behind it and what you say about lifting up women that when we do that, it's not at the expense of men or anyone else that when you lift women, we -- all of society is lifted. Absolutely and I totally believe that. It takes women and it takes men to look at what are the actions we need to take in our home, workplace, community because if you lift up women and then you have men and women equal it changes societies. I've seen it all over the world. The bottom line increases, I mean, not only the right thing to do, it's also just makes sense. If you want to lift people up and want society to be better it works that way. You shared so many beautiful stories of men and women you met on your travels all around the world. There is even a picture -- I think she's from Tanzania. You keep a picture of a woman in your home. Anna was in a loving relationship with her husband and we went to live with them in their home in Tanzania and at the birth of their first son, senari came home and she was sitting on the porch with her suitcase and saying I can't stay anymore. He was heartbroken. She said it's too arid here. I have to walk, you know, ten miles every day to get water and back. I can't nurse our son. I can't cook meals and so instead of moving back to her homeland which was more lush, he said what can I do. She said you could walk to get water which is completely against the tradition. He started walking and other men taunted him and said you've been bewitched by your wife but then other men started walking with him and realized how hard it was and started bicycling and decided to build wells and water pans in their area. Wow. Walk in somebody else's shoes. You name what you need. It takes courage. It does. You revealed some things about yourself. You are -- I don't want to say reluctant in being a public figure. You write about that too because your husband and your family but you knew that the bigger cause you had to step forward. You shared something about before you met bill, before you were married about being in an abusive relationship. Why did you teal that was so important to share. Yeah, that was the hardest part of the book to write by a lot and I have only talked to family and friends about it in recent years but I thought it was important to write because what I realized was I completely lost my voice. I lost my self-confidence and when I go all over the world, places in the U.S., India, different countries in Africa, when I stay and talk to women long enough, it is happening to millions of women and I wanted to write down my stories so people can understand it can happen to absolutely anybody and we need to change that. We do need to change that. In the time that we have left, what is so wonderful, you shared this story about -- because you -- in case -- she's married to Bill Gates. I don't know if you heard that. Oh, by the way. But how the time story. When a friend asked about how you -- two powerful people, how you co-exist and talked about a What bill framed up so beautifully because I think one of our biggest struggles for us in our marriage, how do we allocate our time between us and our three kids and busy lives and what bill said said really beautifully was he reel lieded it wasn't good for either of us to be the time cop even though I felt that way but it's having ared goals for your family and work life that no one is the time cop. Everyone is trying to figure out what is the right allocation given our goals as a family. You heard him say that and you thought, he's got it. Never enough time. I know you'll spend more time online because it is a very important message. It is a thoughtful, thought-provoking, enlightening book and thank you so much for sharing it with us. Melinda Gates.
