"There are easier places to work, but no one has changed the world by 40 hours a week," he said in a tweet.
Tesla's head, Elon Musk, says he knows how many hours a week you have to work to change the world.
"There are lighter jobs, but nobody has changed the world by 40 hours a week," he said in a tweet after saying that SpaceX, Tesla, Boring Company and Neuralink are his ideal job if "getting results is important you."
When a user asked how many hours to work weekly to change the world, Musk said 80 was a sustainable number, with peaks greater than 100 times.
"The pain level increases exponentially over 80," he said.
Comments take place a day after an interview with Axios with Musk on HBO, in which the businessman said that Tesla was a few weeks away from financial ruin during his frantic and costly effort to increase production of the 3-sedan. .
"The company has lost money and if we have not solved the problems in a very short period of time, we were going to die," said Musk, who, as he said, sometimes sleeps in his factory.
