a brilliant one where I can pull the heartstrings of a reader and make them draw closer to the characters because the setting is there, the meaning and theme are clear.
I'd be careful with that affectation. The reader is going to think what they want to think. That can be guided, but it can't be forced. Trying to hard is a great way to write a crappy story.
For me, overcoming this story will push me towards the end goal, because of the harsh words it has faced. I'm not quite ready yet... but how did you conquer a story?
This might not be helpful, but I conquer my stories but not thinking too deeply about them or caring very much whether they work or not. 100% of all ideas are great but maybe 10% can actually be realized. Maybe half of those will be slightly above the garbage level. With everything else writing related, you just have to bang them out doing the best you can and then move onto the next idea.
