Get back to writing
Overcoming writer’s block might be a difficult thing to do, particularly when one has a strong desire to write. Which might seem like a paradox, but it is not: the trick, I think, is to just allow yourself to be in this phase of lack of inspiration, during which your psyche, maybe in a subconscious way, tries to come up with a solution and a very good idea could emerge at some point, if you remain relaxed. But we use to push ourself and therefore accumulate an unnecessary pressure which, in reality, makes your brain to flounder and take more time to do his job, which is counterproductive and something we tend to avoid, and, doing so, the tension only grows and we are in a bigger pickle...
So how not to be caught in such a vicious circle? We just should not ponder too much or, ideally, not at all, which is a very rare, transient state of mind. The first step could involve stopping to call it a “block”, but only a pause for reflection. And who knows if what you come up with after hours of consideration and hesitation, so little and unimportant as it could appear, although hardly earned, isn’t better than what you get effortlessly and rapidly? I guess it will stay an unsolvable mystery unless the machine permitting the alternate dimensions travel is invented.
