The former helps a lot when trying to make sense out of chaos. Even if I haven’t learned a sense of priority, having that list in front of me makes it an easier path to finding priority. And my rule is always if there isn’t any clear sense of priority, then just pick one and ignore the rest.
The latter helps with every-day communication. Repeating things back that I hear helps me remember them, but also can lead to the person or persons you are communicating with deciding what they said wasn’t what they meant. It seems like a small, and probably annoying task, but the amount of times it’s helped me remember something between my co-workers desk and my own so I can record what we decided, or the times it’s led to a convo going just a little bit longer because something needed additional clarification is worth the annoyance, in my opinion.
