Collaboration gets me excited.

Tomorrow is Now... If we act, 2015 can be a year for the history books. It can be the year that we put the world on the path to end extreme poverty; the year we place sustainability at the heart of our future; and the year that we agree that every person should be able to lead a life of dignity and opportunity.

Young people aren't the leaders of tomorrow. They are the leaders of today and tomorrow.

You probably don't think twice about going into your kitchen and turning a few knobs to prepare a meal for yourself and your family on an electric or gas range. But for nearly 3 billion people in developing countries who depend on solid fuels to cook their food, the simple act of cooking results in 4 million premature deaths every year from exposure to toxic smoke.

The resilience and the resourcefulness of people to make a better life, to survive, to give their children something better than they had, is so inspiring. I look at how hard it must be to get up every day and fight that battle and I think, Wow, anything I'm doing just has to be in service.

It's harder to be a poor person than anything else.

One of the things that people aren't aware of is how much progress is being made in eradicating poverty and providing a healthier life and longevity for people around the world.
