Have you tried the sample platter?
Today is going to be a free exercise in writing what ever you like, but here’s the catch. Pick something that is a bit different from what you normally write. Go outside your comfort zone, branch out and try something new. If you write westerns, try adding steampunk into it. Maybe you are into horror, so try mystery sprinkled all over it.
You get the point, find a way to add a new skill to your repertoire. Fill a few pages and then change styles again. Focus on blending the genre’s together with a seamless hand.
