Yeah, my dad grew up very poor and he has worked 10 hours a day, 6 days/week for 30 years without ever being "burnt out".

I sometimes complain about being burnt out and needing a vacation after working for about 3 years, 9-5 max, 5 days a week that includes one day a week working from home.

There is more to life than bills.

Yeah, like food and shelter.

I get that "bills aren't important" is a thing if you don't have trouble paying them, but that's not the situation for everybody. "Hey, lighten up, have some fun, you don't need to work that hard" is cool if you're wealthy. It's an insult to somebody living paycheck to paycheck. They do have to work that hard.

Yes, once the bills are paid.
