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

It's all about patience and persistence - you often have to expose a child to a new food numerous times before he or she will begin to like it. So keep trying!

I try to be thoughtful about spreading the wealth: young designers. Mixing things up is important to me.

What I tell my kids is, I’m preparing you for college and for life. So, having independence, knowing how to set your own boundaries, figuring out how to make that balance. We still have screen time rules.

You know, you have to start with hope...you don't get anywhere in this country without hope. So it's a necessity. What Barack says is that people have to understand hope isn't just blind optimism. It isn't passive. It isn't just sitting there waiting for things to get better. Hope is the vision that you have to have. It's the inspiration that moves people into action...There are more people engaged in this political process in this year than we've seen in my lifetime. And it is all because of hope because people believe in the possibility of something unseen.

Every Thanksgiving, Barack sits down to call some of our troops and thank them for their service. When he tells me about these conversations, it always reminds me of how blessed we are to live in a country where men and women will stand up to protect our freedoms and preserve our way of life. And whenever I've had the chance to meet with these heroes and their families, I've always walked away inspired by their courage and in awe of their strength.

Clearly this is a tough economic time, and a lot of families are hurting. So when we talk to parents, we talk about small changes for kids and things that don't cost extra money. Like adding water and eliminating sugary drinks and sodas. That's going to save money right there. Or adding a few more vegetables.
