I want to feel like the things I did made a difference. That's one of the reasons I spend time greeting people on rope lines, because I'm always thinking, 'Maybe this interaction, particularly if I'm meeting kids, will change someone's life.' That's how I think about the work I do as First Lady. It's a rare spotlight. I want to make sure I don't waste it.

Being healthy isn't about inches, pounds, or how kids look - it's about how they feel and making sure they feel good about themselves. So rather than focusing on appearance, it's important to emphasize to kids that when we eat healthy food and stay active, we feel better, and we can perform better in everything we do, from athletics to academics.

You see, even though back then Barack was a Senator and a presidential candidate... to me, he was still the guy who'd picked me up for our dates in a car that was so rusted out, I could actually see the pavement going by through a hole in the passenger side door... he was the guy whose proudest possession was a coffee table he'd found in a dumpster, and whose only pair of decent shoes was half a size too small.

We need to fix our souls. Our souls are broken in this nation. We have lost our way. And it begins with inspiration. It begins with leadership.

What I love about design is the artistic and scientific complexity that also becomes useful . . . Great designers also pursue a mission. Great designers design with mankind in mind . . . The crossroads of science and art, innovation and inspiration are what I love about design.

I am only as good as my children are.

I am desperate for change - now - not in 8 years or 12 years, but right now.
