I am a sleeper. When you wake up at 4:30 in the morning to do a workout, you're sleepy at 8 in the evening. By 10 o'clock at the latest, I'm in bed.

We have had with Barack Obama some just amazing experiences traveling abroad, being able to introduce our children to the world.... I'm also humbled by the response and the receptiveness, not just here in America, but around the world. There's a part of that warmth and enthusiasm and hope that is surprising and humbling.

My first job in all honesty is going to continue to be mom-in-chief. Making sure that in this transition, which will be even more of a transition for the girls... that they are settled and that they know they will continue to be the center of our universe.

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.

And the first thing we have to do is vote. Hey, no, not just once in a while. Not just when my husband or somebody you like is on the ballot. But in every election at every level, all of the time.

The fact is, with every friendship you make, and every bond of trust you establish, you are shaping the image of America projected to the rest of the world. That is so important. So when you study abroad, you're actually helping to make America stronger.

My ability to get through my day greatly depends on the relationship that I have with other women...We have to be able to champion other women. We have to root for each other's successes and not delight in one another's failures.
