So, why does he wear the same thing every day? When asked this question sometimes back in 2014, Zuckerberg cited a number of psychological advantages to never changing his look.
"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,” said Zuckerberg.
“I’m in this really lucky position, where I get to wake up every day and help serve more than a billion people. And I feel like I’m not doing my job if I spend any of my energy on things that are silly or frivolous about my life.”
Simply put, even making little decisions like what to eat or wear can expend energy he’d rather use on making tough choices for his giant social media to make money.
If you spend hours changing in and out of clothes to post your selfies on Facebook and Instagram, you need to think again, except you are really making money from that.
