A recent trick that has helped me was creating deliberate "chaos" or "mess" areas in certain rooms. By doing so, you tacitly admit that 1) You are not (and you are not intended to be) perfect. 2) There is mess and chaos in your life. 3) Now you know where to find it.
Doing this has brought me great relief. Anything I don't know where it goes, anything I don't have the bandwidth to deal with right now, I know where to put it. Giving it a spacial location is something that connects with your "old brain", thousands of years of training of going to the tree that had nuts, getting your tools from under the correct rock... So it feels very natural and I think it gets some dopamine going.
With all the amorphous blobs corralled into one single spot, you can start to tackle "it" progressively, and what was once daunting becomes often a very nice and stimulating routine. By a few daily minutes of chipping away a couple of random papers, very often you liberate inventory (you become "richer", as you liberate resources that were tied up and producing nothing), and also, the test of time gives you great surprises and even insights about yourself.
An additional advantage of this trick is that, by putting all of it in one place, you get an instant visual control of your chaos levels. As it attracts its dark anti-tidiness matter, one day the initial folder may not suffice anymore and you may have to turn it into a "chaos box". The box perhaps into a "chaos area" in the room. Who knows, maybe you could get at some point to a whole room full of chaos. Still, it's just one room, you know the dimensions of your chaos, and you know where to venture when you have to maybe "rescue" something that suddenly has become important or urgent again.
The journey is also possible in the other direction; at the current pace, one of my chaos boxes will turn into a folder next week, I'm confident that the process of getting there keeps great surprises for me, and also, it feels great...
