Mark Zuckerberg teared up during his commencement speech to Harvard graduates, telling them it is up to their generation to care about others and to fight inequality.
The billionaire CEO returned to Harvard on Thursday to receive an honorary degree - 13 years after he famously dropped out of the Ivy League school to focus on Facebook.
Zuckerberg, now the youngest commencement speaker in Harvard's history, started off reliving some of his college memories.
He told the graduates that he was scheduled to speak to the school board after building the website Facemash, an early precursor of Facebook that allowed students to compare the attractiveness of their fellow classmates.
His parents showed up to the school to help him pack up his belongings, and his friends threw him a goodbye party, where he met his future wife Priscilla Chan in line for the bathroom.
'And, you know, that movie made it seem like Facemash was so important to creating Facebook. It wasn't. But without Facemash I wouldn't have met Priscilla, and she's the most important person in my life, so you could say it was the most important thing I built in my time here.'
