I really believe that with a little bit of information, kids can make a big difference.

My grandmother was determined that everyone feel a sense of optimism and opportunity. Marc and I want to make sure we're doing that. This period of our lives is not just a tribute to her, it's inspired by her. And it's for when we have our own children — I want to help make sure we've got a world I want them to live in.
