I've always been a closet jock. With exercising, the more you do it, the more you get into it. And the more you see results, the more you're pushing for the next level.

Service is a limitless opportunity, it is the reason why we breathe.

My husband and I make physical activity a priority in our lives, and our daughters love being active as well. And while we each have sports and activities we enjoy, we try to go for hikes or bike rides together whenever we get the chance. We've found that the best way to help our girls be active is to find activities they truly enjoy.

I have the privilege of working on the issues that I choose and the issues that I feel most passionate about. It's been a privilege.

I think if I weren't married to [Barack Obama], I'd want him to be in there.

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.

I always want to be on the cusp of being in the best shape that I can be. What I'm discovering is that the older you get, the more work you have to do to stay there.
