Facebook CEO Mark Zuckerberg said Thursday that his yearly personal challenge will be to address the slew of controversies facing the company.

"The world feels anxious and divided, and Facebook has a lot of work to do — whether it's protecting our community from abuse and hate, defending against interference by nation states, or making sure that time spent on Facebook is time well spent," he said in a Facebook post. "My personal challenge for 2018 is to focus on fixing these important issues."

Why it matters: These personal challenges are a key vehicle for Facebook's messaging throughout the year, and it's telling that Zuckerberg has pledged effectively to spend 2018 focusing on his job.
