I have a real conceptual problem with short stories. I'm pretty obsessive-compulsive when it comes to worldbuilding, character development, etc; I don't want to do a throwaway (exaggerating for effect) story when I can go deep with a novel. I'm not a greenhorn at writing prose; I've been writing since my single digits. I just don't finish things. But I hesitate to write shorter pieces if they just don't catch my passion, because I'm unlikely to finish them if I'm just using them to hone my craft and not because I love the stories. Should I write them anyway? Will my first novel(s) likely be trash if I don't?
