During the first campaign, one of my jobs as my husband's spouse was to travel around the country and really listen to women. There were voices that were new to me: the voices of military spouses, many of them women, and veterans.... I was overwhelmed by their challenges, and the notion that we as a country don't even know that these women exist, because we live in a country where one percent of the population protects the rights and freedoms of the other 99 percent of us. I thought that if I had the opportunity to serve as First Lady, I was going to use this platform to be their voice.

The work-life balance is a harsh reality for so many women, who are forced every day to make impossible choices. Do they take their kids to the doctor...and risk getting fired? Do they work weekends so they can afford to send their kids to better childcare...even though it means even less time with their families? Do they take another shift at work, so they can pay for piano lessons for their kids...even though it means they have to stop volunteering for the PTA? It just shouldn't be this difficult to raise healthy families.

But, as potentially the first African American first lady, I was also the focus of another set of questions and speculations; conversations sometimes rooted in the fears and misperceptions of others. Was I too loud, or too angry, or too emasculating? Or was I too soft, too much of a mom, not enough of a career woman?

Good health is multifaceted - it's physical, it's internal, it's my diet, and my emotional state. It's all tied in together.

Barack is one of the smartest people you will ever encounter who will deign to enter this messy thing called politics.

Even if we give parents all the information they need and we improve school meals and build brand new supermarkets on every corner, none of that matters if when families step into a restaurant, they can't make a healthy choice.

I've always tried to make sure that what I do really connects with the broader agenda of what my husband is trying to do.
