Finally you discover how to get things working properly, and then what happens?

Now, a middle-aged or elderly person will have seen it all before - and not only seen it, but survived it. This is why a wrinkly will feel pretty sure that a) whatever happens, everyone will end up where they started, and, b) that there’s no point in wasting energy on new-fangled ideas.
Everyone will manage as they are, and the thing that every kid has to remember is that Mother or Father or Uncle or teacher or priest or Grandad or boss or Great-Aunt or even (most infuriatingly) your best friend knows best.
Sowhat can a heroine do then?
