Elon Musk: This is why I push myself to the brink

Elon Musk has become infamous for his extreme work schedule. When he was ramping up production of the Model 3 Tesla, he put in as many as 120 hours in a week. He slept at the factory because he had no time to go home. He called 2018 "the most difficult and painful year of my career." "[I]t was excruciating," he told The New York Times. In late October Musk finally said he was working a much more manageable schedule of 80 to 90 hours a week.
