I love french fries, I like a good burger, and I like pie. And that's okay. I would be depressed if I felt I could never eat the things that I love. I also don't want my girls to be obsessed about food. We don't have a "no junk food" rule - I just want them to think about their choices.

I'm varying my workouts so it's not just cardio but also includes moves to maintain my flexibility.

This is really what the White House is all about. It’s the “People’s House.” It’s a place that is steeped in history, but it’s also a place where everyone should feel welcome. And that's why my husband and I have made it our mission to open up the house to as many people as we can.

It wasn't so long ago that I was a working mom myself. And I know that sometimes, much as we all hate to admit it, it's just easier to park the kids in front of the TV for a few hours, so we can pay the bills or do the laundry or just have some peace and quiet for a change.

It's always positive to hear how many people are willing to step up - whether it is the employment community, mental health community, or medical community.

For me, being a mother made me a better professional, because coming home every night to my girls reminded me what I was working for. And being a professional made me a better mother, because by pursuing my dreams, I was modeling for my girls how to pursue their dreams.

I always encourage people to start in their own personal universe, because sometimes we as parents start thinking about the big picture. How do I change what's happening in my entire school? And how do I do it in my community? And then you get overwhelmed and it's just like, "Forget it, I'll just stay here in my kitchen and wait." But, start small.
