When your children arrive, the best you can hope for is that they break open everything about you. Your mind floods with oxygen. Your heart becomes a room with wide-open windows. You laugh hard every day. You think about the future and read about global warming. You realize how nice it feels to care about someone else more than yourself. And gradually, through this heart-heavy openness and these fresh eyes, you start to see the world a little more. Maybe you start to care a teeny tiny bit more about what happens to everyone in it.
