He may be one of the richest people on the planet, but in terms of clothing, his choices are very few. The reason for him Mark Zuckerberg, the CEO of Facebook, who every day wears one of the many same gray t-shirts he has in his wardrobe.
The Thursday we passed Mark Zuckerberg participated in the first Q/A organized by Facebook with questions from its own users services. One of those questions was related to his stylistic choices.
Mark, why do you wear the same t-shirt every day?
And while you would expect a humorous answer, Mark Zuckerberg answered very seriously:
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 platforms.
I'm in this really lucky position where I get to wake up every day and help serve more than 1bn 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, so that way I can dedicate all of my energy towards just building the best products and services.
Immediately afterwards, he spoke of a concept that psychologists call it "Decision fatigue". This refers to the idea that people tend to make worse decisions after a time when they have made many decisions.
It is the same philosophy that governs the world of technology in general, as many companies offer their employees services such as free meals and laundry. The fewer decisions you have to make for small things, the easier you will be to concentrate on your work.
