Sometimes if I need to remember something, I wear my wedding ring on my right hand. For the past couple of days I'd added another ring and had left the wedding ring on the left to remember there are two things I need to do. I finally did the the things yesterday. 
Now after a remembering-flood in bed last night and much ring swapping, I wake this morning to find two rings on my right hand (on the same finger). If my calculations are correct, there are four important things that I need to do today, and I can't for the life of me remember what they are.
