You know, fanfic is one of the way to attempt writing. Many afraid to write and those who brave perhaps choose to make their own original story or perhaps they decide to make a fanfic first. Why making a fanfic? It is less stressful since we already have a template. Consider doing fanfic as a learning as well since some (perhaps many) of those who had done fanfics had created their own original stories.
Eh, demon for me. Why? Because it is fun and being a god seems a lot of responsibility.
