There is something satisfying to my mild adhd brain about doing monotonous tasks. I used to work in a candle factory, and one of my tasks was cutting birthday candles to size and packaging them. In on 8 hour period i would package ~8000 candles into ~70 shipping boxes. Start the day with a pile of empty boxes and end the day with a pile of full boxes.

There is something very zen about the point at which you don’t even have to use your eyes anymore because the motions were so second-nature. Other people found it eye-wateringly boring but I thought it was peaceful.
