We have an obligation to fight for the world as it should be.

I was out there meeting with a lot of working moms and whenever I would gather a group of women, there was always a voice that was unfamiliar to me, and it was the voice of a military spouse, oftentimes a woman, oftentimes working, many times in a position where they've had to move every two or three years, where their kids have had to change school multiple times, people dealing - families dealing with multiple deployments, dealing with the stresses of reconnection.

We have to design policies that have meaningful impacts on the quality of life of women and families. And that's something that I know I can speak passionately about because whether I'm in the White House as First Lady, as long as I have kids and I'm trying to have a life, I'm gonna be trying to make this balance work...

America is just downright mean.

When I get up and work out, I'm working out just as much for my girls as I am for me, because I want them to see a mother who loves them dearly, who invests in them, but who also invests in herself. It's just as much about letting them know as young women that it is okay to put yourself a little higher on your priority list.

Every Thanksgiving, Barack sits down to call some of our troops and thank them for their service. When he tells me about these conversations, it always reminds me of how blessed we are to live in a country where men and women will stand up to protect our freedoms and preserve our way of life. And whenever I've had the chance to meet with these heroes and their families, I've always walked away inspired by their courage and in awe of their strength.

I was an incredibly devoted student, and I would often wake up at 4 or 5 in the morning to study. But even so, there were still people who thought that a girl like me with a background like mine wasn't really "college material."
