The bulletin board, the “like” button, the shares, the tags: Facebook seems to have always been there, yet that is not the case. So how did we all end up on there? To answer this question, let’s travel back in time a few years, until we find ourselves in the room of a college student: Mark Zuckerberg. That’s where everything, or almost everything, started. It is a story of personal successes and battles, moments of glory and blunders, of surprising planning and absurd strokes of luck. Offers involving exorbitant, dizzying figures will flit by. And we, together with Mark, will turn them down. Because Facebook is not just a company, it’s a mission.
