Billionaire businessman Elon Musk announced he has returned to a grueling schedule of working seven days a week and sleeping in the office. In a post on X (formerly Twitter), Musk on Sunday described himself as being in “wartime mode," a term he uses to signal periods of intense focus and nonstop effort during critical phases at his companies.

Known for his extreme work ethic, the Tesla boss shared an old video reflecting on the toll such a work life has taken on him. Admitting the routine is painful and harmful, Musk said, “No one should put these many hours into work. This is not good. This is very painful. It hurts my brain and my heart."

What’s led Musk to return to this tight work routine again is the pressure mounting across several of his ventures. These include ongoing developments at X, ambitious timelines at Tesla and SpaceX, and bold plans in AI and government reform.

Notably, this is not the first time Musk has adopted such a demanding work schedule. In several interviews, the billionaire has admitted that he works relentlessly whenever required.

In 2018 interview with CBS’ 60 Minutes, Musk had revealed he adopted a challenging task of working for 120 hours in a week during Tesla’s Model 3 production crisis. During that period also, he slept on the factory floor to lead by example, he said.

Musk’s current return to this intense lifestyle comes amid mounting pressures at several ventures, including Tesla, SpaceX, X, and new projects in AI and government reform. He recently claimed that his team at the Department of Government Efficiency (DOGE) also followed a 120-hours workweek, far outpacing “bureaucratic opponents" who work only 40 hours.

Musk’s relentless work style is not only restricted to him but to his employees as well. After acquiring Twitter in 2022, he demanded staff commit to “long hours at high intensity" or face consequences. Reports surfaced that Twitter’s San Francisco office was converted into makeshift dormitories—dubbed the “Twitter Hotel"—prompting an investigation by the city’s Department of Building Inspection. Musk responded defiantly on X, criticizing the city for targeting companies that provide beds for exhausted workers rather than focusing on protecting children from fentanyl.

Throughout his career, Musk’s extreme dedication has been both praised and criticized, reflecting the high stakes and personal sacrifices behind his ambitious ventures.
