On Sunday Elon Musk said he had turned social media company Twitter around, and it was “trending to breakeven” after he saved it from “bankruptcy.”

He added that the past three months had been “extremely tough,” as he ran his new $44 billion social media company, in addition to his responsibilities as CEO at Tesla and SpaceX.

He concluded, “Wouldn’t wish that pain on anyone.” 

Previously Musk has described himself as a “nano-manager” who sleeps very little, going to bed late after working long hours. He also suffers from physical pain, apologizing during testimony at his federal trial in San Francisco in January for “squirming around,” by explaining he has “quite severe back pain.” He has had several surgeries for neck and back pain which he attributes to an injury he sustained throwing a 380 lb sumo wrestler while at a party once.

Tesla investors have worried that Musk has been distracted by his responsibilities at Twitter, however Musk has dismissed the criticisms, noting he has attended all important meetings at Tesla, and adding, “I still do a lot of work at Tesla!”

He has noted he goes to bed at around 3 a.m., and only sleeps six hours. In 2018 he slept at a Tesla factory on the floor, and more recently he has taken to sleeping at Twitter’s offices in San Francisco.

After running a Twitter poll asking if he should step down as CEO of the social media giant, and receiving a result indicating 57.5% of more than 17.5 million voters polled wished for him to do so, Musk tweeted he would bring in another CEO “as soon as I find someone foolish enough to take the job!” However there is no word on how the search for a successor has gone, and Musk has offered no timetable on any proposed transition of power.
