I think that’s when we really find out exactly where our writing level is at, when we push ourselves outside of our comfort zones. Staying in your comfort zone is safe but I personally think your writing can stagnate if you do that. Writing for different genres forces you to think differently, approach things in a way that you wouldn’t have before. My biggest Achilles Heel is coming up with plots that I’m happy with. I find it very, very difficult, which is frustrating.
I’m glad you enjoyed my story. And you should definitely have a go at writing horror one day. It’ll be good experience if nothing else.
