I find this can calm my anxiety about forgetting something important. Back in the 90's I used a Franklin Day Planner which was pretty awesome but also a bit too prescriptive for me so it was equal parts useful and repulsive :-). But I found I could capture the things I felt were important on paper and worried less about them being lost.
That turned into writing into my notebook at night what questions had come up during the day, and what needed doing. And in the morning, reviewing that and picking the top three things on that list to be addressed that day.
