Sleep is for the weak… and so is salt.
Thomas Edison was very outspoken about his sleep schedule- or lack thereof. He felt that power naps were far superior to taking long ‘normal sleeps.’ Also, he refused to hire anybody who seasoned their soup before tasting it.
...and Tesla, too
Edison never said that about salt.
That was J.C. Penny, who used to take jr. executives up for promotions to lunch and watch whether they seasoned their food before eating.
His belief was that they wouldn't be careful in company decisions if they acted impulsively at simple eating decisions.
