This doesn't acknowledge weekends, which if you have the same 8 hours sleep and 4 hours "not for yourself", add more than 50% to the time you supposedly have "for yourself". (4×5 + 12×2 vs 4×7.)

Which doesn't necessarily change the point, but I'm not sure what if anything the point is supposed to be, and it seems an important omission.

Don't usually have much extra time on the weekends. Weekends are for making up for a week of the house getting dirty, relatives and friends wanting to meet, extra long walks for the dogs that only got short walks during the week, errands that got put off, some catchup sleep, actually relaxing a bit since there wasn't much during the week, etc.

I might have 2-3 hours each day (of energy and motivation) to work on projects but not 8. Of course I never have 4 hours during the week either, I'm lucky to get 1 in usually.

> relatives and friends wanting to meet

which is why some people who have the discipline and self-control to do a big personal project often have to neglect friends and family - it's a sacrifice.

youre not alone. Unless i actively maintain my apartment itll deteriorate over the week (i even meal prep weekends to alleviate some) i do agree with others though. More time spent disengaging from the work your doing may actually net you a positive in the productivity dept

Weekends aren't necessarily free time.

Saturdays and Sundays are chore days, or family days, or simply resting, or ...

About 4h remaining for yourself is still fairly realistic.

I assume that for most people the "not for yourself" time is bigger on the weekends, it is for me and the people around me.

Indeed. In my case, ever since I became a parent, I consider weekends a total write-off.
