I've noticed that I get the same amount of work done working 5 days a week as if I plan to only work 3/4 days and know I'll have some free time to enjoy life. My work is really project based so as long as it gets done no one cares.
My wife has also noticed that I'm a lot more stressed when I work 5 days a week and need pretty much the whole weekend to recover.
When my title changed from web developer to software developer I got a 60% pay increase, but my job hardly changed in reality. I still only make just enough to do doordash on the side as an extra safety net and not as a necessity to afford food.
But when anyone asks what I do for work and I tell them, they immediately assume we're absolutely loaded and I'm picking up the check everywhere we go.
