Sometimes the issue is about whether families and communities think girls are even worthy of an education in the first place. It's about whether girls are valued only for their labor and reproductive capacities or for their minds as well. And it's about whether women are viewed as second-class citizens or as full human beings entitled to the same rights and opportunities as men.

My goal has always been to add value, not to be redundant, not to get in the way, but to do things that lift and move things forward in a very strategic and objective way so that there are real outcomes.

I love french fries, I like a good burger, and I like pie. And that's okay. I would be depressed if I felt I could never eat the things that I love. I also don't want my girls to be obsessed about food. We don't have a "no junk food" rule - I just want them to think about their choices.

Our kids didn't do this to themselves. They don't decide the sugar content in soda or the advertising content of a television show. Kids don't choose what's served to them for lunch at school, and shouldn't be deciding what's served to them for dinner at home. And they don't decide whether there's time in the day or room in the budget to learn about healthy eating or to spend time playing outside.

Kids who participate in school meal programs get roughly half of their calories each day at school. ... This is an extraordinary responsibility. But it's also an opportunity. And it's why one of the single most important things we can do to fight childhood obesity is to make those meals at school as healthy and nutritious as possible.

This year, 1.7 million young people will be participating in Olympic and Paralympic sports in their communities-many of them for the very first time. And that is so important, because sometimes all it takes is that first lesson, or clinic, or class to get a child excited about a new sport. This summer, together with our children, we can support Team USA not just by cheering them on, but by striving to live up to the example they set.

The biggest obstacle facing girls is education, education, education. There are too many kids who think high school is a pit stop to fame and fortune. I want girls in this country to think education is the coolest, most important thing they could ever do in their lives.
