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...

In fact, in the last job I had before coming to the White House - I remember this clearly - I was on maternity leave with Sasha, still trying to figure out what to do with my life, and I got a call for an interview for this position, a senior position at the hospitals. And I thought, okay, here we go. So I had to scramble to look for babysitting, and couldn't find one.

I talk about the food issue, I'm really coming at it from pre-White House times, when I was a working mother with a busy husband, a very demanding job and two little kids to feed.... I had to learn what it means to feed and care for your kids in a country where fast food is abundant, where time is a rarity, where eating out is a trend, because families are so busy.... Yes, I'm First Lady, but I know the struggles.

I was blessed throughout my entire career. I had people rooting for me. It started with my parents, but it extended to almost every teacher that I had.

Although the circumstances of our lives may seem very disengaged, with me standing here as the First Lady of the United States of America and you just getting through school, I want you to know we have very much in common. For nothing in my life ever would have predicted that I would be standing here as the first African-American First Lady.

I have a very eclectic iPod. So I've got my cardio people - so it's anything from Beyonce to some Jay-Z to Janelle Monae, her song 'Tightrope,' that's a good cardio song. And then I've got Sting. I've got Mary J. Blige. I've got The Beatles. I've got Michael Jackson. I try to pick the songs that I personally love.

My mother's love has always been a sustaining force for our family, and one of my greatest joys is seeing her integrity, her compassion, her intelligence reflected in my daughters.
