People who really want to make a difference in the world usually do it, in one way or another. And Ive 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 a 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 small changes add up . Sometimes they even transform cities and yes - - the world .”
