I worked an average of 60-80 hour weeks for about 5 years. If you really truly enjoy what you do, then it's really not that bad if you don't mind work being basically your entire life. It was largely responsible for my divorce, but I was able to balance a social life after that even though I was usually in the office 6 days/week for 10-12 hours/day.
I could totally work 80 hours a week. If someone else did all my house keeping, yard work, childcare, and I had all the Red Wings games beemed directly into my brain.
Where is my hockey games beamed to my head Mr Musk?
Didn't all the tech guys like him promise a life of leasure and little to no work, cuz tech?
It would be nice of these guys all had their heads mounted on pikes.
This is simply ridiculous of Musk to say. People generally have plenty of other things to do in life besides work.
People generally do not change the world.
Commenters in this thread do seem to have glossed over the "to change the world" part...
Do you really need 1000 people working 80 hour weeks to change the world or 2500 working 40 hour weeks? Musk keeps more money per the same amount of "world changing" in one of those scenarios.
Man whose entire identity and fortune is work says more work is good. Man whose entire identity is drinking says more alcohol is good.
