Editing
E is for editing...
Editing is just as important as the story itself. I myself not only use grammarly, I also have an editor. As a self-published author I put myself under a stronger microscope to make sure I am presenting the best work I can. Now of course we are all human so mistakes are going to be missed but holding myself to a higher scrutiny because I don't want to be one who takes short cuts just to get my books out without doing the double and triple checks.
You should always have a minimum of three checks for editing. This way you have done your do diligence in making sure you have dotted all your i's and crossed all your t's. I produce my stories for myself as much as for the readers but to do my best not only for my work but to provide the best of myself for the readers.
As a creative type, writing is my artistic outlet but I also want to present the best work I can, even if there are only a handful of readers who read it.
