Answer and Explanation:
To be frank, I believe that it is impossible to utterly avoid writer's block. In a writer's career, one is bound to hit a roadblock where they simply cannot conjure new ideas or lead on the storyline, try as they might.
Despite this, there are a few ways that can mitigate this issue:
- Find a place, person, or object that you've always found inspiring to you or that always manages to calm you (usually it is a specific location). There, sit down, perhaps meditate a bit, clear your mind. Maybe something will come to your mind.
- Write down a list of words or phrases or ideas that rapidly come to mind, no matter how ridiculous or irrelevant they are. Perhaps later when you come back to this piece of writing and see this list, you may be able to create a few connections.
- Set down the piece of writing for a while; take a break from it. Perhaps begin another story with a totally new/different plot. Once you've refreshed your mind from this one, return and you'll likely find yourself and your place again.
Inevitably, you will find your way back on track and continue with your writing. There truly is nothing you can do to totally prevent writer's block.
Hope this helps!
