New Zealand Prime Minister Jacinda Ardern's announcement that she would step down as the country's leader by February shocked many of her constituents and leaders around the world.
"I'm leaving, because with such a privileged role comes responsibility," the 42-year-old Ardern said in her announcement on Thursday local time. "The responsibility to know when you are the right person to lead and also when you are not. I know what this job takes. And I know that I no longer have enough in the tank to do it justice. It's that simple."
