Taking a break may help bring that Eureka moment, but what part does the unconscious play?
Mental blocks are incredibly irritating.
It doesn’t matter whether you’re pondering spreadsheets at work, trying to decide what colour to paint the shed or wondering where to spend the holidays, sometimes you hit a mental block and can’t go forwards.
It might be that the number of options is overwhelming or, at the other extreme, that you can’t come up with a single idea. Either way you’re stuck and in that moment there seems like no way out.
