I bullet journal. (https://bulletjournal.com/pages/learn) I got my wife into it as well. Our journals are vastly different. She uses it to review and keep info. I use it as a task list and some notes.

It's a big motivator and important tool I've picked up.

The best part of the bullet journal method is the de-prioritizing of tasks. I don't give up on things to the point of detriment. With a bullet journal, I've learned to let go of stuff and move forward.
