The social network's co-founder celebrated the online platform's 14th birthday on Sunday (04.02.18) with a post addressing the mistakes he has made while working at the head of the company.
He said: "Over the years I've made almost every mistake you can imagine. I've made dozens of technical errors and bad deals.
"I've trusted the wrong people and I've put talented people in the wrong roles... I've missed important trends and I've been slow to others. I've launched product after product that failed."
Mr. Zuckerberg added that he wanted to constantly improve, and never stand still as he looks to the year ahead.
He continued: "We are still early in this journey and we will keep working to improve. That focus has always been our strength, and that's what this year is all about."
It comes after he announced plans for a big overhaul in what Facebook users see on News Feeds and plans to make it more orientated towards family and friends rather than businesses.
Zuckerberg wrote on his Facebook page: "One of our big focus areas for 2018 is making sure the time we all spend on Facebook is time well spent. We built Facebook to help people stay connected and bring us closer together with the people that matter to us. That's why we've always put friends and family at the core of the experience. Research shows that strengthening our relationships improves our well-being and happiness. But recently we've gotten feedback from our community that public content - posts from businesses, brands and media - is crowding out the personal moments that lead us to connect more with each other ...
"Based on this, we're making a major change to how we build Facebook. I'm changing the goal I give our product teams from focusing on helping you find relevant content to helping you have more meaningful social interactions. We started making changes in this direction last year, but it will take months for this new focus to make its way through all our products. The first changes you'll see will be in News Feed, where you can expect to see more from your friends, family and groups."
