Hope is necessary. It's a necessary concept. And Barack Obama didn't just talk about hope because he thought it was just a nice slogan to get votes.

We're [President Barack Obama and I] clear on the fact that we have to stay humble and prayerful. We have to dig down deep to our roots. When things come together, we know some of it is Barack, some of it is us-but a lot of it has nothing to do with either of us.

That's the advice I would give to women: Don't look at the bankbook or the title. Look at the heart. Look at the soul. Look at how the guy treats his mother and what he says about women. How he acts with children he doesn't know. And, more important, how does he treat you? When you're dating a man, you should always feel good. You should never feel less than. You should never doubt yourself.

I had the honor of meeting a young Pakistani woman named Malala Yousafzai, who was shot and nearly killed just for trying to go to school. I also heard about how nearly 300 girls in Nigeria were kidnapped from their school dorms in the middle of the night. There are girls like this in every corner of the globe. In fact, there are more than 62 million girls worldwide not attending school, and that's an outrage.

You've got to keep your body active, even if that means just turning on some music and dancing for an hour. ...That's how you;ll prepare your bodies and your minds for greatness.

I want to send a very clear message to the men and women who are wearing - or who have worn - our country's uniform and to their spouses: when you have finished your service to our nation, you've got 2,000 great American companies ready and waiting to bring you on board

Childhood obesity isn't about looks. And it's not about weight. It's about how our kids feel. And those are really the implications of the problem and the words that tell a fuller picture of the challenges that we face; you know, kids struggling in ways that they didn't a generation ago.

For me exercise is more than just physical, it’s therapeutic.

Since we started the Let's Move! initiative, I've been looking for as many ways as possible to help families and kids lead healthier lives. And I've come to realize that if we were going to take just one step to make ourselves and our families healthier, probably the single best thing we could do is to simply drink more water. It's as simple as that. Drink more water.

When I was a young lawyer, there were other women and men in the firm who took me under their wing. Sometimes mentors don't find you - sometimes you seek them out. You shouldn't hesitate to plop herself in someone's office and ask them to be that support.... Oftentimes, they're flattered and glad to lend a hand. So I would encourage any reader to seek out a mentor, then follow through and be very focused and persistent.

I mean, that's the least we should do for these men and women [veterans and military spouses], is to make sure they come back to jobs that pay, to career opportunities, that these spouses are able to add a second income to their households, because these families do not have a lot of resources.

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.

My husband and I make physical activity a priority in our lives, and our daughters love being active as well. And while we each have sports and activities we enjoy, we try to go for hikes or bike rides together whenever we get the chance. We've found that the best way to help our girls be active is to find activities they truly enjoy.

An educational foundation is only part of the equation. In order for creativity to flourish and imagination to take hold, we also need to expose our children to the arts from a very young age.

Our job is, first and foremost, to make sure our family is whole.

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.

Barack, like any leader, is human.
And, you know, our challenges in this country isn't finding the next person who's gonna deliver us from our own evil.
Because our challenges are us.
The challenges that this country faces is how are we as individuals in this society gonna change?
What are we gonna do differently?

I don't, as my mom would say, sweat the small stuff in our relationship. Because when I think of day-to-day irritations that you might have with the one you love, they're nothing compared to the bigger task at hand.
