The Facebook CEO has declared a goal each year since 2009. Past challenges have included wearing a tie every day, learning to speak Mandarin and eating meat only from animals he killed himself. Last year, he visited every U.S. state he hadn't been to yet.
This year, though, his challenge is directed at his company rather than personal ambitions. Zuckerberg wrote Thursday that he wants to focus this year on protecting Facebook users from abuse, defending against interference by nation-states and "making sure that time spent on Facebook is time well spent."
In other words, he wants to do his job as Facebook's CEO.
"This may not seem like a personal challenge on its face, but I think I'll learn more by focusing intensely on these issues than I would by doing something completely separate," Zuckerberg wrote.
He added that while Facebook won't prevent all mistakes or abuse, "we currently make too many errors."
Facebook had a tough 2017. It testified before Congress about its platform being used for Russian election meddling and drew harsh criticism from early employees and investors about its role in the world.
