I do it the way you do, Juni. Plus notes on the back of my hand. Always. i'm known for that. People like to check how far up my arm my notes go to see how busy my day has been!
Notes and lists everywhere. Not all of it gets done. In fact most of it doesn't on any given day, and i rarely actually need to refer to my lists -I tend to check them near the end of the day to make sure i didn't miss anything that had to be done that day....but for me, once it's written down, I can stop stressing about forgetting it and devote my brain to other purposes. It's a stress-reliever.
