I used to write all the time, but after two long Dragonball Z stories, I found myself feeling quite burned out. It took a while, but slowly I'm starting to get back into the swing of things again, so maybe now that I've started posting again I'll get around to fixing the millions of glaring problems with my DBZ stories... eh, maybe not.
Anyway, I always try to finish everything I start, so even if I don't update for a while, the story will be finished, someday.
Right now my Naruto story, Time and Again, is the only thing I'm really working consistently on, though I occasionally fiddle around with a DBZ: Trunks-Pan story that's been rattling around in my head for months and on a Vegeta-Bulma story that I've been thinking about for years. Both of those are just on my computer and will probably remain there for the foreseeable future, but who knows?
