If you do not wish to repeat yourself, the essential thing may be not to worry so much about what you’re writing, but what you’re reading and experiencing. As you continue you to learn you continue to change. As you change your style will change. As you read things you haven’t read before, by authors you haven’t read before, in styles you haven’t read before, your understanding of what can be possible in literature will constantly expand. During the last few years, expanding what I read has dramatically changed me as a writer.
