similarly from dune re leadership... it's just a simple thing but the idea that once you tell a group of people under your leadership to do something once, you have to tell them to do the thing every time. Thus good leaders give as few commands as possible. I've found this broadly applicable any time i have to tell more than one human at a time what to do and in assessing leadership in other people (mostly bosses I've had. The best ones have been hands off but approachable when what needs to be done is obvious and very hands on when teaching/introducing something new until everything is clear, then back to hands off). It even works when you're trying to train a dog.
