I'd imagine he has an impressively comprehensive team around him ensuring he doesn't need to focus on anything other than his work.

That said, working over 14 hours per day 7 days a week is implausible to me. Maybe in short bursts but I doubt he does that for any stretch of time.

The Elon Musk PR machine & cult of public enthusiasm is a massive business asset. When you're in the business of selling dreams to investors and employees pushing themselves to the limit this type of 'fact' is going to get thrown around.

'Work' can include things like travel and lunches. Both of which can be downtime but are classed as 'work'.

Overall its hard to believe considering he also has Space x and other investments and im suresomeone is streching the truth. But I dont doubt the guy lives and breaths his work.

Bill Gates was reputed to work that much as well, and I don't think anyone disputed it either.

self-reported and therefore not reliable.

some executives never stop working, even when not on site they consider time spent solving problems in their head or sitting at their computer/tablet/etc as work.

myself I have been around some six to six executives who even at parties talk shop. hell we used to joke that when one went on vacation it only made his emails longer

[dilemma]

Yes, I'm sure they do and I would too but that is not the vernacular "working".
