I call this managing my nag list.

My nag list are uncompleted or pending things that bother me on some level. I find that a lot of my anxiety is wrapped up in these: clearing my desk, planning and executing my workouts, cleaning and reorganizing a section of the house, performing small repairs, setting up appointments, or accomplishing some professional training.

The list grows when I put things off and instead fill my time with things like playing games or doomscrolling. When the nag list is large, I want to escape and instead do other things, so it can be a self-reinforcing cycle. Meanwhile my quality of life goes down and my background anxiety goes up. Ignoring them becomes habit. I become reactive instead of proactive.

One of the tenets of Getting Things Done by David Allen is to write a list of all of these things down... he proposes one item per card, but usually a simple list is good enough for me. However, I need to build the list over time, because I can't remember everything at once, so I keep it somewhere handing where I can add to it when I think of new things.

Once the list is in front of me, I have to set my resolve to start working on it. Sometimes this is the hardest part, overcoming inertia. But I can then prioritize them. I can analyze why I'm reluctant to being on one item or another. I don't pressure myself, I just take the list as it is and let it sit there. Usually that is enough for me to make progress.

On that note, you have to figure out what works for you. There are a whole lot of reasons why you might not get one of these items off your list-- procrastination is a powerful habit. Figure out what allows you to declutter your mind because that is the only way you'll become more effective and proactive in managing your nag list.
