i think you sure write what you want to write and build your foundation there, rather than write what you know people what to read. Your right, it help you develop as a write because it's what you want to come out of it. And I think it'll be easier because you don't have to understand the person that you're writing about. :) I made that decision a long time ago, which is why I didn't post up my story for R5. However, if I finish my other fan fiction that's not up here soon I think I'll post that because it would be done by then. >.< Good luck on your writing and may you be blessed with the ideas that no one else has given to the world yet.
