True, there are elements of good writing: character, conflict, dialogue, idea, mood, plot, scene, style and world; but when I'm in the mood to start a story I will generally begin with nothing at all. And then I write a word. From that word, I get a sentence. Then I build a paragraph in a style that reflects how I feel at the time of writing.
By the end of the paragraph, I will generally have the glimmering of an idea and a character (or two) will have strolled into view. Because there is a view I will have to describe the scene. The way that the characters inhabit the scene will set the mood. If the characters seem like they want to say something then there will be dialogue. Sometimes the dialogue leads to conflict, but if not then I will inject it at this point.
From this foundation, I will continue to lay down paragraphs to build up the world layer by layer. Something always occurs to me to write - word by word and line by line. Sometimes the characters tell me what they want to do and at other times the conflict tells the characters which direction to run.
It's not until I get to within a couple of paragraphs of the end that the actual ending suggests itself to me and when it does, I simply aim my writing towards that goal and complete the arc of the plot simultaneously.
Generally, at this point, I will go back and either delete or radically alter the first paragraph because usually, it will have no bearing on the rest of the story. I then scan through the rest of the tale adjusting internal consistency, grammar and syntax as I go.
Then I read it all back making any minor adjustments as I progress. Then I'll read it aloud. Then I'll get the programme to read it back to me. Then I'm done. Maybe I'll involve others at that point. Maybe not.
I write everything in WordPress usually. I have Grammarly installed and this checks my prose for basic stuff like spelling and accurate comma placement.
