If you run the world’s largest social network, how many hours can you expect to work a week? In a new Q&A, Facebook CEO Mark Zuckerberg suggested he puts in 50-60 hours a week… at most. “I spend most of my time thinking about how to connect the world and serve our community better,” he wrote, “but a lot of that time isn’t in our office or meeting with people or doing what you’d call real work.” He added: “I take a lot of time just to read and think about things by myself. If you count the time I’m in the office, it’s probably no more than 50-60 hours a week.” Even when he’s not in the office, thinking about Facebook’s mission is “basically my whole life.” Granted, a CEO with thousands of employees probably has an easier time balancing a schedule than, say, a startup founder who needs to handle every aspect of the business them self; contrast Zuckerberg’s schedule with the hundreds of startup mavens who spend 70 or 80 hours a week (if not more) trying to keep their endeavor alive. But if Zuckerberg can maintain an effective work-life balance, than most people can do the same. Image: Facebook
