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.

I struggle with distraction and procrastination, making it feel like nothing gets accomplished on average, even though there are some small steps each day.

I have a kanban/whiteboard with small post-its and the "done" column is a reminder that things are being completed, even if not always at the pace I'd like. Not so much a hack as a reminder to not be down on yourself - we can't all be hyper-focused life hackers :-)
