What is the most detail-oriented activity you enjoy?
Where there’s a huge number of details to get right and you just have to patiently work through all of them, and you either genuinely enjoy it or it feels like a soul-crushing grind?
It's the equivalent to me of rearranging furniture in a room so the rug ties it all together, but in a good way.
Workflows for web design would be the flip side. Have to whip myself into a frenzy of hyperfocus to get anything accomplished there.
