I am only as good as my children are.

Childhood obesity isn't some simple, discrete issue. There's no one cause we can pinpoint. There's no one program we can fund to make it go away. Rather, it's an issue that touches on every aspect of how we live and how we work.

Some kids have never seen what a real tomato looks like off the vine. They don't know where a cucumber comes from. And that really affects the way they view food. So a garden helps them really get their hands dirty, literally, and understand the whole process of where their food comes from. And I wanted them to see just how challenging and rewarding it is to grow your own food, so that they would better understand what our farmers are doing every single day across this country and have an appreciation for ... that American tradition of growing our own food and feeding ourselves.

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.

Always stay true to yourself and never let what somebody says distract you from your goals.

He’s always asking: ‘Is that new? I haven’t seen that before.’ It’s like, Why don’t you mind your own business? Solve world hunger. Get out of my closet.

When it comes to the health of our families, Barack refused to listen to all those folks who told him to leave health reform for another day, another president. He didn't care whether it was the easy thing to do politically - that's not how he was raised - he cared that it was the right thing to do.
