Take a quick glance around almost any parking lot in America, and you're sure to see at least one bumper sticker with the phrase oft-attributed to Gandhi: "Be the Change You Wish To See In The World." People yearn to make a difference in the world they live in. The million dollar question, however, is: how, exactly? 

"We think that there are so many people out there who want to make a difference, and indeed two-thirds of Americans donate to charities every  year," says Nicholas Kristof, columnist for theNew York Times and co-author, along with his wife Sheryl WuDunn, of the new book "A Path Appears: Transforming Lives, Creating Opportunity." "But often I think people feel overwhelmed by the scale of the challenges and don't really feel that their checks or their volunteering are accomplishing that much."

That's where Kristof says his new book comes in: pointing people in the direction of actions that may seem small, but have huge impact. "In fact, there is a lot of evidence about the kinds of things that do work to create opportunity both abroad and at home," he explained. "We wanted to give people suggestions about things that really can make a difference."
