1) Read books. Lots of them. 2) Don't write what you know. Write what you love. Write what your soul screams to release. 3) Find a constructive critique group. Then find a good place to get feedback from strangers. Wattpad is good place to start. 4) Write all the time. Practice makes permanent. Find your strengths and weakness in terms of your craft. 5) Seek out other writers in the community or on the internet. You will find a trove of resources that will help you get better, learn about craft, about market, about querying, about how to find an agent, how to build a platform, and all the other less sexy elements of being a writer. 6) Develop an inner editor. Give that editor a personality. Is he a stubborn fact-checker? Is she a grammarian first and foremost? Does she delve into the story looking for ways to improve the writing style or the story development? Edit with that personality, not your writer's brain. Be ruthless. Use the eyes of another to see your story from a different perspective.
