Figure out what you want to write. The large field of creative writing splits into subcategories (fiction, poetry, creative nonfiction) and there are even specialized genres (sci-fi, mysteries, experimental… the list goes on).
Figure out what you want to write. Write what you would want to read. Your best writing will spring forth from something that you, and maybe only you, are passionate about. No one can write the way you write. When your passion is injected into your writing, your readers will, in turn, be interested.
