If he weren't his own boss, Mark Zuckerberg would have been fired from Facebook, he says.

"So one of the things that I've been lucky about in building this company is ... I kind of have voting control of the company, and that's something I focused on early on. And it was important because, without that, there were several points where I would've been fired. For sure, for sure," the 35-year-old multi-billionaire CEO said in leaked audio from internal meetings published in part by The Verge on Tuesday.
