This new year brings new projects—and some sad goodbyes. Today, I’m excited to begin my leadership of Sister Cities International, the world’s largest and oldest network of citizen diplomats. And I’m sorry to leave the Wilson Center, which has been my home for the last five years. But it’s not a long goodbye: I will continue to work with the Global Sustainability and Resilience team as a Global Fellow and as an advisor to the New Security Beat. In all of these roles, my New Year’s resolution is to renew our commitment to making a real difference in global well-being and sustainability. And while this year promises great changes, three key priorities will continue to inspire me and guide our collective efforts: resilience, complexity, and diplomacy.
