I guess I’ll dip my toes in this thread too.
I’ve been writing fiction sporadically for about four years now. Some people on this forum and Kazamatsuri already know about my FanFiction.net page, but I also write original works as well. I tend to alternate between the two when I come up with new stories, although because I have a lot of ideas in the backburner, I tend to write what I feel most invested in. My genre tendencies sway between science fiction and urban fantasy, although occasionally I like to dabble in other genres to mix things up.
I’m averse to sharing my story ideas in particular, and I still have a lot to learn as an author, but I’m willing to share some advice if people need it. I do think that writing is very much driven by how the author feels about a particular subject. If a story doesn’t evoke any sort of feeling from the reader outside of apathy, why should it exist? Stories like Umineko compel the reader because it evokes emotion. Joy, laughter, discomfort, love, sorrow, fear, anger. If you currently feel any of these or other emotions towards something or someone in particular, channeling that feeling into writing may be a good practice. Just something to think about.
