I make “to-do” lists all the time. I try to do them electronically, but the most successful ones are just written on a pad with a pen, and completed items get struck off the list.
My wife also makes lists of things to do, but when she does that, I tend to think of it as “her list”, not my list. If there was something on her list that I was going to do, I would add it to “my list”
So, it is important when making a list to consider “Am I doing the things on this list, or do I think someone else is going to do things on this list?”. It would be good to have direct communication with anyone you have an expectation of doing something on “your list”.
I do have things on my todo-list that I marked as delegated or to be delegated. The difference between the two being whether I reached out to the other person about doing it.
