Watch Sheryl Sandberg Pay Tribute to Her Late Husband in Commencement Speech

Sheryl Sandberg paid tribute to her late husband Dave Goldberg in her commencement address Saturday at Beijing’s Tsinghua School of Economics and Management.

The Facebook COO offered four key points of leadership in her speech, one of which is that nothing should ever solely be someone else’s problem.

“Yes, people will do what their bosses tell them to do in most organizations,” Sandberg said. “But great leaders do not just want to secure compliance. They want to elicit genuine enthusiasm, complete trust and real dedication. They don’t just win the minds of their teams, they win their hearts.”

“No one won more hearts than my beloved husband Dave Goldberg, who passed away suddenly two months ago,” she continued about Goldberg, who was 47 at the time of his death. “Dave was a truly inspiring leader. He was kind. He was generous. He was thoughtful. He raised the level of performance of everyone around him. He did it as CEO of SurveyMonkey, an amazing company that he helped build. He did it for me and for our children.”

Sandberg shared a quote from a friend who described Goldberg as having “showed us all exactly what being a great human being looks like … but it was never frustrating because Dave’s greatness was not competitive or threatening. It was gentle, inspirational and egoless. He was the quintessential standard for the notion of leading by example.”
