I think in the end, I want to make sure that my kids come out of this thing on the other end in one piece. But I also know that that's how the rest of the country feels as well, so for that I am grateful.

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.

That's where you just have to get creative. There are all these trampoline parks and there's bowling and there's roller skating.

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?

See, that's why Barack's running: to end the war in Iraq responsibly - to build an economy that lifts every family, to make sure health care is available for every American - and to make sure that every child in this nation has a world-class education all the way from preschool to college.

I always encourage people to start in their own personal universe, because sometimes we as parents start thinking about the big picture. How do I change what's happening in my entire school? And how do I do it in my community? And then you get overwhelmed and it's just like, "Forget it, I'll just stay here in my kitchen and wait." But, start small.

One thing that I've learned from male role models is that they don't hesitate to invest in themselves, with the view that, if I'm healthy and happy, I'm going to be a better support to my spouse and children. And I've found that to be the case: Once my kids were settled, the next thing I did was take care of my own health and sanity. And made sure that I was exercising and felt good about myself. I'd bring that energy to everything else that I did, the career, relationship, on and on and on.
