Learn the why behind the rule. Then you’ll follow it on the days nobody’s checking.

A rule you have only memorised depends on somebody watching, because once nobody is checking there is nothing left holding it up. A rule you understand survives alone, since you can see what goes wrong without it and you can also tell when it genuinely does not apply. Understanding converts obedience into judgement. That is the difference between following a procedure and being trusted with one.

Pick one rule at work or school that you follow without knowing why, and ask somebody. If the reason is good you will keep it more easily. If nobody can give you one, that is worth knowing and worth raising politely.
