Having always loved English, I should’ve guessed I would’ve wanted to write at some stage but in many ways it’s not how you start as a writer that matters, but the fact you keep going. You also need to keep reading - classics, in your genre, out of your genre, contemporary (you’ve got to know what else is out there).
Don’t rely on the computer’s spell checker.
It doesn’t pick up on everything. Mine has a bit of a thing about wanting to put in “his or her” instead of “their”!!!! What has it got against “their”?!!! Have a good dictionary to hand, always.
Vary sentence and paragraph lengths to vary pace.
One continual pace is a monotone, never interesting. Watch out for favourite words and phrases creeping in - this is where a good edit comes to your aid!
Think about why you write the way you do.
Can you improve it? Look for favourite phrases - they will creep into your writing unbidden! Mine do! Is your style appropriate for what you’re trying to produce? For example light, easy sentences might not be apt for a dark piece where I’d expect the words to be heavier, darker, to conjure up the right mood. Wodehouse stuck to what he knew - humorous prose - for a good reason. And his light style is perfect for it. Likewise horror writers write in a very different style appropriate for their work. So make sure your style matches.
Are you getting into the heads of your characters well enough? If someone asked you an unexpected question about any of them, could you, based on your knowledge of them, answer it?
Is there enough going on in your story? Do your characters change? Do you show how and why? That is the story after all!
I like writing games too. Great exercises and who knows what stories they might lead to.
Ernest Hemingway once came up with the perfect six words short story - “For sale, one pair of baby shoes”. If that doesn’t get you wondering what happened, nothing will. But in itself it hints of tragedy and of a short story, possibly a novel behind it. So I’m going to have a go at coming up with mega-short stories like this. If I’ve got this right, I think of it as subject, action and/or reaction. To start with:-
He refused to cry again.
She told him about the cliff edge.
The explosion solved their problems.
The vampire stole the blood donor van.
