With writer's block, no.
with keeping productive, and to continue writing, yes.
If you are looking elsewhere to fix your story while you have writers block, then it's not writer's block. Because being able to write another story zero problems, means you can and are able to write, and have those creative feels thrown down onto paper.
If you can't continue with the current story and ONLY the current story, its a problem with that story.
Either
you wrote yourself into a corner
you don't know where you want to head with the plot
you dont know your characters enough
maybe you just don't care for the genre but enjoy the characters and the scene?
something is wrong with that story that is stopping you from continuing. you need to figure out what that reason is.
starting another story is a distraction from that story. You're either trying to fix it, or pausing only to forget the problem exists. deciding if you want to have that story in your library, or not, comes with writing. authors drop books, drop stories, and that's fine. but if you really like this story, then you have to figure out why you don't like it.
talk it out.
Writer's Block: Does writing a novel on the side allow you to refresh your mind?
So, I've been reading that people sometimes write two novels because it allows them to refresh their minds to go back to their main novel or whatever.
Should I try to do that?
Of course, I won't post it, but should I try it to see if it helps me?
in this small block of text. you didn't even mention why you would want to bother writing something else or the reason for your block.
I think reasoning is important.
if you dump the book, and turn to another, without understanding why, you'll repeat this process more often than you realize until 20 books down the road you start figuring these things out about yourself.
