I don’t disagree , but there’s still the issue of different natural day-night rhythms. Night owls vs early birds.

Some people will need less discipline and motivation than others to achieve this.

Not to undermine the discipline of anyone who actually makes it happen.

Care to take some of my hours, lol?

I need to sleep 10 hours, every night, otherwise I’m actively depriving myself of sleep. I’m not ill, got confirmed that that’s just how it is. A 40 hour work week really wasn’t made for this.
