I don’t know any billionaires but I knew some extremely wealthy people and they def worked for it. One only slept from 1-5am, we knew because of their email and document edit times. Also had to supply them with satellite internet while they hiked up to my Everest base camp so they could keep working. Dude was intense but literally built an empire in his industry by himself.
People that were already multi-millionaires at birth? No idea.
This is also my impression of some billionaires. I found this article about the work ethic of some famous people: https://www.inc.com/business-insider/work-ethic-of-super-successful-people.html
I’m not buying 180 hour work weeks, that only leaves 38 hours or so for meals, bathing, etc. I’m not buying 100 hour work weeks for 24 years, either. I am curious what industries need graveyard shift receptionists that aren’t illegal industries.
It was interesting about the sports people, and may or not be believable.
Their hobby is working. Thats the difference.
