My counter to this instinct, which is obviously less accurate, but perhaps more snappy is:
Always do everything.
In particular, if it comes to a choice between doing something and not doing it (as opposed to a choice between doing something and doing something else), you should always choose to actively do. Obviously, there are likely to be budget constraints, but it’s only supposed to be a guideline.
