I'd bet that a lot of that in-camp work didn't feel excessively laborious when it was done while socialising within your group, and without a sense of "wish I was playing video games". Sitting around a camp fire now whittling away at something is more mucking around than chore.

Sure sitting around a campfire and whittling away at something now feels more like mucking about than chore, because it is. You don’t actually need whatever it is you’re whittling. It would probably be less relaxing if your survival depended on your handiwork.
