I used to keep a small notebook.

I'd have a new one for each year. The rolling aspect kept things off my mind as someone else mentioned. I'd note everything in there. But more recently I moved everything to digital. I keep an iPad pro with me at all times, and I use apple notes. I create a new note for each month, labelled Oct 2018 for this month for example, and keep the rolling tasks list going for that. I keep all of them in a notebook labeled "Daily Notebook". Apple notes lets me access it from more places, and share sketches digitally, and it's free (obviously except for the initial expense of the tablet).
