Writing fanfic is satisfying but it's not fun. It's work. Even the hilarious crackfic...maybe it's the perfectionist in me, but I'm always thinking about "Am I getting this right?" The characters speak to me, but it's work to translate that into entertaining prose.

And when it comes to angstier work...it can be pure torture to get that onto the screen or the page. Worth it, oh god yes, but not fun.
