I like to log everything I do in a log file. I use OneNote for this as it is very easy to create checkbox lists.

I start the day by creating a new day title with the date and then add empty checkbox items for the things I want to get done, then I move over stuff from the previous day that I did not get around to yesterday.

And I also have a list at the bottom for stuff I need to do eventually but is not a priority, I review this list every morning as well.
