Here is why Mark Zuckerberg wears the same thing every day

This sounds like an over simplification for something that requires minimal effort. I wake up, shower, grab a pair of shorts off the top shelf, grab a polo / printed t-shirt off the shelf just below it. Yesterday I wore a light blue t-shirt with a multi color (but mostly blue) pair of shorts; today I have a black t-shirt with orange shorts. The decisions took me 10 seconds to make, most of which was multitasking color choice while putting on a watch and deodorant.

Your appearance says volumes about you - some of us may take it further; i'll match the color on my Apple Watch face to the majority clothing color I'm wearing (so orange today) but again, takes seconds to do and doesn't require much thought, if any.

Once upon a time, this society didn't leave the house without a suit or a dress on; now your lucky if most people are wearing clean clothes I guess.

Few others too seem to have the identical reason for similar behaviour: http://elitedaily.com/money/science-simplicity-successful-pe...
