Rumor has it that Thomas Edison (progenitor of the 99% namesake) would sleep just 4-5 hours a night and then power-nap in order to intentionally access the super-creative powers of the theta state. Edison would grasp a ball bearing in his hand, which he draped over the arm of his chair just above a tin pie plate. As he nodded off in his chair, he’d drop the bearing, and the clanging would wake him up just as he drifted off. Then, he would immediately write down whatever was in his mind.
…maybe why you feel most productive when you wake up at 4am?
