Resources

Never had any formal training on writing and don’t know where to start? Gotham Writer’s Workshop has tons of resources. The ones I used when I was starting out are the books, Writing Fiction and the Fiction Gallery. This combo of books gives you a rundown each part of writing, an example from the gallery, and then an exercise where you try it out yourself. The Elements of Style is a good rule books as well.
Looking to tighten your craft? Ursula K Le Guin’s Steering the Craft is a book for writers who want to level up. No more beginner writing guides. Want to really get a grip on using semicolons? Use this book. Like the Gotham Writers Workshop books, this comes with lessons, examples, and exercises. I’m a hands-on learner. Try and make each exercise you do a piece of micro fiction or a short story. I got a lot of useful material out of the exercises this way—and writing smaller enhances your craft a lot when you write bigger.
Looking to get even better at novel crafting? Use the brain science book Story Genius by Lisa Cron.
Looking to decolonize your writing? Use Craft in the Real World by Matthew Salesses
Need to get over a hurdle? Not a writing guide, but the NaNoWriMo Pep Talks archive is sure to have something to help.

Their websites and social media. Above ones should be to hunt generally. Go to their websites once you find them to make sure they’re a good match for you and so you can create a good bond open in your first paragraph about why you want to work with them. Finding an agent isn’t about finding someone to open the gate to traditional publishing; it’s about finding a business partner and a friend—someone who loves your work and will champion it to the business world.
