Marcus Lemonis is the CEO of billion-dollar company Camping World and has invested in more than 100 businesses.
So when CNBC recently asked how much time he puts in each week, we weren't surprised to learn that the traditional 40-hour workweek doesn't exactly cut it.
"Rather than asking how many hours I work a week, you'd be better off asking me how many hours I sleep a week," said the star of CNBC's "The Profit." "I probably sleep 35 to 40 hours a week."
He said he's on "the 40-hour program" — just not in the way you'd expect. He sleeps 40 hours a week, and works the rest of the time.
But for Lemonis, the nonstop work schedule isn't drudgery; it's fun.
