The Science Of Simplicity: Why Successful People Wear The Same Thing Every Day "Our life is frittered away by detail... Simplify, simplify. - Henry David Thoreau" "This is all related to the concept of decision fatigue. This is a real psychological condition in which a person’s productivity suffers as a result of becoming mentally exhausted from making so many irrelevant decisions. Simply put, by stressing over things like what to eat or wear every day, people become less efficient at work. This is precisely why individuals like President Obama, Steve Jobs, Mark Zuckerberg and Albert Einstein decided to make life easier by adopting a monotonous wardrobe."
