Eventually every writer has to accept that their idea of a finished story often has nothing to do with a publisher’s concept of a story worth buying. When submitting a particular piece, the rejections generally start to make you question your writing ability but that is a self destructive approach. Once a publication passes on the story that you felt was perfect for them, taking any criticism and using that to re-polish the work is much more beneficial.
Unfortunately a lot of editors do not have the time to offer advice and just send out a standard rejection. In these cases it is up to the writer to sit back down and start picking through the story to see if there are improvements that are still needed. And often there is at least one issue that can be fixed.
I myself have a tendency to start my stories at the wrong spot. What begins as a 6,000 word tale needs at least a couple thousand cut, or rearranged and pieced back together to add that extra edge that makes my work stand out. It was hard at first, but I have gotten so accustomed to going through and mutilating the original finished copies of my stories in order to make them palatable that it is now part of my process. If readers could see what has been changed to get one of my pieces published….oh the thought of it is terrifying.
But the improvements made to have your words translate better to wider audiences is always worth it.
