I quit at 35 and am now 58. My only regret was being too afraid to do it earlier.
How ? I long ago was able to to differentiate needs from wants.
I do own my own small house. Each year I have excess funds, some is rolled over and reinvested, some is donated to charity, because the small investments I do have earn way more then my needs.
I’d consider euthanasia if I had to return to work because of some unforseen reason, after deaades of freedom Arbeit macht frei is prison.
