Lots and lots of self employed people are not "working" 24h/day.Where does this myth come from? Is it corporate propaganda?

"No one ever changed the world at 40 hours a week"
"80 hours minimum, with peaks at 100 hours"
A 100 hour week would be 16.6 hours for 6 days and 1 day off, or 14.25 hour days with no days off
The idea that entrepreneurs need to work more than 40 hours a week to be successful is as old as our industry, and I'd go so far as to say that those casually working a schedule that looks more like a salaried position are probably "consultants" and aren't really entrepreneurs trying to build something or change something
But I've worked at many startups and ok 50 hours would be common. As they say, one pregnancy takes one person 9 months. You can't do it in 4.5 with two people (or by working harder).
