Attach a review date to every automation you build
When you finish building an automation, set a specific future date to come back and look at it again, even if nothing seems wrong by then. Write that date down where you will actually see it.
This matters because "review it eventually" never happens on its own — it needs a specific trigger, not a vague intention. An automation with a review date attached gets a fair check-in regardless of how busy things get, instead of being forgotten simply because it never caused loud enough trouble to demand attention. This is different from a general habit of checking automations now and then — it is a specific promise tied to that one build. I put that date on my own calendar the same day I finish building, because I know I won't circle back otherwise.
Put the date on your calendar the same day you finish building, while the automation is still fresh in your mind.
Try this today: pick a review date for the last automation you built and put it on your calendar right now.
