Stephanie Klinzing, the mayor of Elk River, Minnesota, challenged the people in her town to perform 1,000 acts of kindness in a month. Elk River's 24,000 residents answered the call, with good deeds like giving out cookies, paying for other people's groceries, and babysitting for free. After a month the people of Elk River had surpassed their goal with 1,400 good deeds -- and they don't plan to stop anytime soon.
