Are you naturally a short sleeper? Do you stay up late and wake up early and not feel tired? A small group of the total population, about 1% to 3%, have the sleepless elite gene (aka an amazing superpower) that enables them to hack their sleep cycle and only sleep 2-6 hours a day. These members of the sleepless elite never oversleep or sleep in, even on weekends. They only need a few short hours of sleep per day.

So what do they do while everyone else is sleeping? Members of the sleepless elite are some of the most successful members of our society. Instead of using their extra time at night for recreation, many short sleepers focus on productive endeavors. From tech founders and presidents to TV hosts and politicians, here are some of the most famous members of the sleepless elite in history.

1Jim Cramer, host of CNBC’s Mad Money and founder of TheStreet.com
