I recently had a discussion with a friend about genre jumping when writing and it left me curious about other opinions about the subject. My friend and I talked about two major schools of thought on the subject. The first is that you should stick with what you know and are best at, as it would ensure that your writing is better. The other is that a writer can't grow if they stick to the same thing. Have you any different options about it? Also do you genre jump or do you stick to the same ones? Why do you do that?

I'd really appreciate any comments as that little conversation has ignited my curiosity.
