If you are going to write, say, fantasy - stop reading fantasy. You’ve already read too much. Read other things; read westerns, read history, read anything that seems interesting, because if you only read fantasy and then you start to write fantasy, all you’re going to do is recycle the same old stuff and move it around a bit.
