Set aside time to try to break your key automations
Once in a while, set aside real time whose only purpose is trying to break your most important automations on purpose. Throw odd input at them, disconnect a step, simulate a tool being down, and see what actually happens.
This matters because regular use tends to follow the same familiar paths, which means the untested corners of an automation can stay hidden for a long stretch of ordinary operation. A dedicated stress session forces those hidden corners into the open while you are paying full attention, instead of letting a real customer stumble into one during a normal day. It feels unproductive in the moment, since you are not building anything new, but it is some of the most valuable time you can spend on a process that other people depend on. I block this time off on my own calendar now, since the corners that stay hidden during normal use are exactly the ones that cause real trouble later.
Treat this like routine maintenance, not an emergency response, and it stays manageable.
Try this today: block off a short session this week purely to try breaking your most relied-on automation on purpose.
