The Journal report noted that Musk has a history of working long hours, and even sleeping on a Tesla TSLA, +2.52% factory floor — leading Arianna Huffington to once write him an open letter begging him to get more rest, because “people are not machines.” (He tweeted back at her at around 2:30 a.m., countering that working less is “not an option” for his businesses to succeed.)
But the past few months have been especially grueling, as Musk revealed while testifying in federal court in San Francisco about his 2018 “funding secured” tweet and other posts where he claimed to have already secured funding to take Tesla private. (A jury found him not liable this past Friday.) At one point during this Tesla trial, he told a lawyer, “I had trouble sleeping last night, so unfortunately, I’m not at my best.”
He later added, “I’m sorry for squirming around. I have quite severe back pain.”
This back pain stems from him reportedly squaring off against a sumo wrestler during a birthday party years ago, when Musk says that he managed to actually throw his 350-pound opponent at the cost of “8 years of mega back pain.”
But he also told investor Ron Baron at a conference last November that, since taking ownership of Twitter, his workload has ballooned from around 80 hours a week to more than 120 hours. “I go to sleep, I wake up, I work, go to sleep, wake up, work — do that seven days a week,” he said. “I’ll have to do that for a while — no choice — but I think once Twitter is set on the right path I think it is a much easier thing to manage than SpaceX or Tesla.”
Musk elaborated in his tweets over the weekend that while Twitter is not financially healthy yet, he’s optimistic that “it’s trending to be,” although there’s “lots of work still needed to get there.”
