If it ain’t bolted down: Read everything- scripts, poems, novels, non-fiction, web content, tweets, even text messages. Highlight things you like, incorporate it into your unique blend until it feels like all your own.
Channel your heroes: There's another exercise where you write the same scene as if you're a different writer. Shonda It.
Phone a friend: ASK people who know your writing and see what resonates with them and what stands out.
Act up: Take an improv, acting class, try standup, do a podcast.
Be a Dictator: Dictate your writing and then listen to it.
YOUR POV: Your perspective on the world, how you see it, and how your background influences the types of stories you tell and what your characters say and do.

YOUR THEMES: The common themes that come up in your work, regardless of genre. It is what you’re trying to say about the human/animal/robot/alien experience.
