Facebook chairman Mark Zuckerberg said his goal for 2018 was to put the company he helped set up on more solid ground.
Zuckerberg, 33, one of the richest people in the world, wrote in a publication on the world's first social network: "The world is nervous and divided and Facebook has a lot to do."
In the past years, his decisions for the new year included learning Mandarin, reading two books a month and traveling to the US he had never visited.
This year, Facebook described its stand at a crossroads that required its attention. He cited the spread of hate speech through social media and the use of Facebook by Russia and other countries to spread biased media propaganda, as well as criticism that Facebook could be a waste of time.
A new law in Germany calls on social networks such as Facebook and Twitter to remove online hate speech or face fines. In the United States, lawmakers criticized Facebook for failing to prevent Russian elements from using its platform to intervene in the 2016 US election.
In addition, Facebook executives have publicly raised questions about whether the use of the network leads to unhealthy behavior.
Zuckerberg said his personal challenge in 2018 was "to focus on reforming those important issues." He said that the pledge "may not appear to be a personal challenge on the face of it," but he will learn a lot and did not say what he will learn.
"We will not prevent all errors or abuse, but we are doing a lot of actions that impose our policies and prevent the abuse of our tools," he wrote.
