Writing relies on very few things, my friend. All you need to write is your brain, a way to convey the story into existence (pen, computer, whatever), and a place in which to do it (office, kitchen table, lunar brothel).
Chuck WendigWrite like you write, like you can't help but write, and your voice will become yours and yours alone. It'll take time but it'll happen as long as you let it. Own your voice, for your voice is your own. Once you know where your voice lives, you no longer have to worry so much about being derivative.
Chuck WendigWhen in doubt, the rule of threes is a rule that plays well with all of storytelling. When describing a thing? No more than three details. A character's arc? Three beats. A story? Three acts. An act? Three sequences. A plot point culminating in a mystery of a twist? At least three mentions throughout the tale. This is an old rule, and a good one. It's not universal - but it's a good place to start.
Chuck WendigCharacters exist in a flat line until we challenge them - sometimes they challenge themselves, sometimes they're challenged by other people, by nature, by robots, or by fungal infections in and around one's nether-country. Stories need conflict across the physical, emotional, intellectual and spiritual spectra. Accidents, betrayals, cataclysm, desperation, excess - these are the letters in the alphabet of conflict.
Chuck WendigQuestion the Chestnuts. Chestnuts: the new name for boobs? No. NO. Why would you even say that? Get your mind out of the gutter. No, by "chestnuts" I mean, "those old pieces of writing advice that you hear as common refrain." 'Write what you know.' 'Adverbs give Baby Jesus hemorrhoids.' 'If you write a prologue, an orphan loses his sight.' All the "old saws" need to be put on the chopping block.
