Elon Musk says he has 'no option' but to work so hard at Tesla that his personal life is ruined

Elon Musk says he is unable to work proper hours, even if his habits are causing him serious damage in his personal life.

The Tesla boss has been called on by people including Arianna Huffington, who said that he needed to adopt a healthier work-life balance. But he said such a decision was not an option.

The comments came after Mr Musk conducted a wide-ranging interview with the New York Times in which he detailed the stress of running his company and the ways it was ruining his personal life. He broke down as he described not celebrating his own birthday and nearly missing his brother's wedding.

But in a tweet early Sunday after arriving home from a late night at a Tesla factory, Musk told the Huffington Post founder that his electric car company and Ford are the only two American automakers that have avoided bankruptcy.

He then added, in an apparent reference to his long hours at work: "You think this is an option. It is not."

Mr Musk was responding to an open letter from Ms Huffington on Friday in which she called on him to change the way he works so he can ensure he's taking more time to "refuel and recharge."

Mr Musk conceded in the interview that he's overwhelmed by job stress, has been working up to 120 hours a week and sometimes takes Ambien to get to sleep.

Tesla has presented plenty of challenges for Mr Musk. The company routinely loses money and is burning through cash as it ramps up development of its Model 3 sedan, a less-expensive electric car it hopes appeals to the mass market. A large number of investors known as short-sellers have bet against the company.

Mr Musk, who recently said he might take Tesla private, has added to those pressures with lofty projections for profits and production that the automaker often fails live up to. Plus, the eccentric billionaire is the head of at least two other companies, including the rocket company SpaceX.

In her open letter, which referenced Musk's interview with the Times, Ms Huffington urged Mr Musk to ease up on the long hours at work.

"Working 120-hour weeks doesn't leverage your unique qualities, it wastes them," she wrote. "You can't simply power through — that's just not how our bodies and our brains work."
