Since the first Global Citizen Festival in 2012, countless influential artists, business leaders, and politicians have graced the event's stage. Global Citizen, co-founded by Michael Sheldrick, has helped distribute more than $43 billion to end extreme poverty. The organization has also been working with Rotary for over a decade. As Global Citizen prepares for its annual return to Central Park this year, Jennifer Jones sat down with Michael to discuss his inspiring story, the transformative work of Global Citizen, and his new book, "From Ideas to Impact: A Playbook for Influencing and Implementing Change in a Divided World."
