In that free time I built businesses and today I sometimes just work an hour a week. And I never loved working as much as I do now. And honestly when I do working weeks at maybe 30 hours a week I am still way more productive than I ever was with 40 hours.
If you ask me the whole system is broken. Working 40 hours a week shouldn't be normal, sure if people want to why not, but it shouldnt be the usual offering, it shouldnt be the amount people need to work to have enough money for that little free time that is left.
Also starting at 8 o clock. I mean what the fuck is that? Nobody cares about the % of people who are way more productive at evening and need a long sleep. It's completely up to oneself to find a way to adapt in this world
