Mark Zuckerberg’s five-word motto “move fast and break things” spawned Meta’s multibillion-dollar success and inspired an entire generation of Silicon Valley entrepreneurs.

It’s also terrible advice, according to Harvard Business School-trained leadership expert and author Anne Morriss. In a TED Talk earlier this year, Morriss decried the idea behind Zuckerberg’s phrase, suggesting instead that CEOs and leaders everywhere should “move fast and fix things.”

That’s easier said than done: The motto exists because doing things quickly tends to make people skip double-checking their work, and Zuckerberg wanted to prioritize speed over perfection in his company’s early days.
