I’ve noticed something about people who make a difference in the world: They hold the unshakable conviction that individuals are extremely important, that every life matters. They get excited over one smile. They are willing to feed one stomach, educate one mind, and treat one wound. They aren’t determined to revolutionize the world all at once; they’re satisfied with small changes. Over time, though, the small changes add up. Sometimes they even transform cities and nations, and yes, the world.

Write hard and clear about what hurts.

Sometimes, you read a book and it fills you with this weird evangelical zeal, and you become convinced that the shattered world will never be put back together unless and until all living humans read the book.
