I spew plenty of advice all the time, especially when it comes to writing.
So here goes nothing.
The first sentence of your story should make readers want to read the second. So on and so forth.
Try to establish a conflict or some kind of tension as early as possible. If you can do so in the first paragraph, fantastic. If the conflict arises on page one hundred and ninety-nine, you may want to revisit everything before it.
What's necessary? What isn't?
Clean up your messes. It's fine to info dump everything in your head on the page the first time around, but take care of them when you come back to edit.
If you listen to nothing else I say, for which I don't blame you, hear me out on this: you are not obligated to follow anyone's writing advice. Listen. Learn. But you are your own writer.
What works for you may not work for someone else. Similarly, what works for others might not work for you. So you should do what works best for your own writing.
Make your reader care. Give them a reason to. Many even.
Dare to say something different. Think about what others are saying and say the complete opposite. Play devil's advocate.
Never neglect any element of storytelling. Create a compelling character or twenty. Throw them into a messy situation with conflict. Advance your story's plot at a good pace. Establish setting, location. Think about themes.
When you're stuck, consider the five senses. What can your protagonist see or hear? How do they feel? Does he or she smell something strange? Don't forget about taste.
Be unpredictable. Do the unexpected. Surprise yourself and subsequently your readers as well.
Take writing one word at a time, one day at a time.
Writing an entire novel or 100,000 words can seem daunting.
But writing 1,000 words or one page every day for a year isn't so bad.
I'm a broken record, aren't I?
