We can do better than good. Together, we can be great. As Martin Luther King, Jr. put it, "Everybody can be great, because anybody can serve." In honor of MLK Day and President Obama's National Day of Service, we're challenging you to commit yourself to service. Spend one percent of your work hours this year (that's 20 hours) changing a small corner of your world for the better. However you choose to give back, this year you can be great. Click "Do It" below to take the pledge, and let's dig in!
