This week, leading innovators, communicators, and advocates from the international development community came together in New York for a “master class” to share stories, ideas, and inspiration on how to make progress on our international challenges.

The class coincided with the UN General Assembly, the Social Good Summit, and the adoption of the new global goals for sustainable development. Over two days, these humanitarians gathered to share what they’re doing — and what needs to be done — to help the world achieve these global goals and build a better future for people and planet.

Below are five quotes you should hear from the sessions:
