His tool of choice? A New Year's resolution.
This year, he wants to fix Facebook's hardest problem: He wants to end the abuse of the platform, whether through election-interference efforts, fake news, or other nefarious practices.
That resolution took Zuckerberg on a tour of the country that included visiting the Emanuel African Methodist Episcopal Church in Charleston, South Carolina, where a white supremacist killed nine black worshippers in 2015. He met people recovering from opioid addiction in Dayton, Ohio, and hung out with a dairy farmer in Blanchardville, Wisconsin.
His first resolution, in 2009, was also focused on his job: wear a tie every day.
"That first year the economy was in a deep recession and Facebook was not yet profitable," Zuckerberg wrote in a Facebook post on Thursday. "We needed to get serious about making sure Facebook had a sustainable business model. It was a serious year, and I wore a tie every day as a reminder."
But many of his resolutions focused more on personal growth - the kind of resolutions that any of us might make. Here's the full list, in case you need inspiration to take on a New Year's resolution of your own:
- 2009: Wear tie daily
- 2010: Learn Mandarin
- 2011: Be a vegetarian or only eat meat if he killed the animal himself.
- 2012: Code daily
- 2013: Meet a non-Facebook person every day
- 2014: Write a thank-you note daily
- 2015: Read a book every two weeks
- 2016: Build an artificial intelligent app for his home and run 365 miles
- 2017: Meet someone from every state
- 2018: Focus on fixing Facebook's abuse problems.
- 2019: Hold public debates on the effects of technology on society. etc.
- 2020: No more public disclosures of annual goals but more focus on long-term projects.
