We Millennials have grown up. We've gone from passionate teens to professionals, flexing our leadership muscles in the workplace. We still carry the idealism of our younger years, but, with our new roles as movers and shakers, the stakes for our involvement are much higher. This is our world now -- and we need to be ready to help take charge. This week in New York City, the United Nations will adopt the new Sustainable Development Goals, a set of goals and targets designed to end extreme poverty over the next 15 years. They're universal, and so are expected to guide the policies and practices of all countries, not just the developing ones. As a Millennial, I'm keeping a watch on what our governments and organizations do, and looking for ways to help.
