How Motherhood Changed 15 Amazing Women

"People ask me what's the best thing you've ever done, the hardest thing you've ever done? The answer is the same: It's being Chelsea's mom," says Senator Hillary Clinton. "When Bill started running for the White House, my only condition was that we do whatever we could to protect her, because it's a very hard life for anybody who goes into it. I kept saying 'no and no and no', and people finally realized that I meant it—and they have given her a chance to be who she is today. I'm most proud of the fact that she is an independent person with a loving heart. She's a wonderful young woman. I'm very grateful for that."
