Third is Humility. You, I, and everyone else is ordinary. We all have the power to forge a world through writing and imagination. Since we are all normal, if I find something interesting, there is a high probability that many people are going to find it interesting too.
Fourth, grammer and punctuation. Short answer, use grammarly. That software is really useful. There might be alternatives but I have forgotten them. It was only until I started using grammarly, I started to see the amount of mistakes I was making.
Fifth, don't try to remove something extra before looking for an opportunity to integrate them. What I mean by that is, sometimes when we write, we might put something extra, like a character or an analogy that you think will not make sense or become irrelevent as the plot progress. But perhaps wait a few moments before typing backspace, 'is there a way to make a path to suit this 'extra'? Will that path be fun to write?' If answer is yes, you might get an even better story.
Last but not the least, I will say, 'power breaks'. This one like all these other rules is what worked for me the best. After posting a chapter, I would take a few days break. This might be different from other authors' advice to write consistently. I would say experiment with them.
Bonus tip: Be 'water'. Don't be constrained by all these principles and be flexible with yourself. You might find out that consuming too much content might create noise in your head, or you words just flow from your hands when you turn on music matching the content you are writing, but you wouldn't know until you have tried them both.
That's all I can say. Hope it helps .
While writing about this, I myself have gained some clarity over some principles. So, thanks for that.
