I also don’t strictly distinguish between work days and other, but you also clarified that the time shouldn’t include chores which are work too but not usually associated with work for money or education so I had to make some cut. If you had included any kind of productive work the number would have read differently. Lots of pleasure reading e.g. LW can count as such; the line (or factor) could be how much it contributed to your own future development.
