Let me guess: When you have a task to start say filing a pile of unfiled mail, bills etc, you start by sorting it into other piles and then run out of time, over time those piles grow, then at some point get combined then (after a suitable grieving period) you have a task to tackle this pile, so you start by sorting it into piles...
I totally understand the concern about organization paralysis, but the point is to keep it simple, focused, and relaxed. By writing things and ideas down in an organized way I don't have to track it in my head, and I can get back to what's important. Or at least procrastinate on something useful. I suppose it looks complicated from the outside, but has really only grown slowly over a decade.
Also: I have most bills on autopay, and transactions created 90d in advance in GNUCash. I do also have piles of mail in the form of a filing cabinet and labeled folders. I've actually been experimenting with letting the mail pile up in an inbox and filing it away once a month just to prove to myself the system works enough that I don't have to monitor it daily.
