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.

The realities are that, you know, as a black man, you know, Barack can get shot going to the gas station, you know.

All we can do as women is make the best decisions for us. And that includes everything from how you look to how you dress to whether you choose to stay at home or work when you have kids. All those decisions are so personal, and we have to start with finding what brings us joy and what brings us our own individual confidence. And if we're feeling good with those choices, then it makes what everybody else has to say less important.

I tell this to my girls all the time: This journey we're on is a once - in - a - lifetime opportunity.

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 always want to be on the cusp of being in the best shape that I can be.

I have never felt more confident in myself, more clear on who I am as a woman. But I am constantly thinking about my own health and making sure that I'm eating right and getting exercise and watching the aches and pains. I want to be this really fly 80-90-year old.
