Facebook CEO Mark Zuckerberg was asked the question: “Hey Mark, why do you wear the same drab grey T-shirt every day?”

Zuckerberg is worth $35 billion. BILLION. He could happily wipe his a** with your yearly wage if he wanted to. But he explained: “I really want to clear my life to make it so that I have to make as few decisions as possible about anything, except how to best serve this community.”

He’s not the first person to have possibly done this. Obama, for example, apparently always wears a blue or grey suit. The same could be said for Albert Einstein and Alfred Hitchcock.
