I'm not a big fan of young kids having Facebook. It's not something they need. It's not necessary.

I like to talk about my obsession with french fries because I don't want people to think that 'Let's Move' is about complete, utter deprivation. It's about moderation and real-life changes and ideas that really work for families.

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.

We're all bombarded with so many dietary messages that it's hard to find time to sort through all this information, but we do have time to take a look at our kids' plates.

In fact, in the last job I had before coming to the White House - I remember this clearly - I was on maternity leave with Sasha, still trying to figure out what to do with my life, and I got a call for an interview for this position, a senior position at the hospitals. And I thought, okay, here we go. So I had to scramble to look for babysitting, and couldn't find one.

The fact is, with every friendship you make, and every bond of trust you establish, you are shaping the image of America projected to the rest of the world. That is so important. So when you study abroad, you're actually helping to make America stronger.

I believe that each of us-no matter what our age or background or walk of life-each of us has something to contribute to the life of this nation.
