Every job has a mixture of low impact and high impact tasks.
Both tasks are necessary to be done, but perhaps the high impact tasks are more meaningful and personally satisfying.
The chef needs to clean the grill (low-impact), but takes delight in making a roast dish (high-impact).
So, it pays to improve productivity on the low-impact stuff, leaving more time for the high-impact duties.
I’m going to tease out this idea a bit more. Perhaps the terminology is wrong; some smaller tasks (chopping onions) actually enable other tasks (making bolognese).
