I'm wondering if there's a word or phrase to describe an action or activity which turns out to be pointless – let me explain further with an example;
Recently I was organising the garage and had lots of bits of wood lying around which I needed to store properly, so I made some shelving with the wood. In so doing, I realised I had used up all the wood which I needed to store – so the shelving I had created was sort of redundant and unnecessary. However, had I not have built the shelving I would still have lots of bits of wood lying about the place which would need storing.
I wondered if there is a word, phrase or expression to describe this sort of futile paradoxical activity?
