writing

Since I'm very recently getting back into this kind of thing, and was never truly experienced in creative writing as its own beast anyway, I'd just like to ask those who have been consistently doing this for a while: What things should I avoid as I get back into Roleplay? Or as an expansion...

I'm sure we all have pet peeves when it comes to reading other peoples work (even our own), so let loose here! I find that I'll be flicking through fanfic or even books in a store and I see that the author has a habit of doing x annoying thing. I promptly close the book/page and go elsewhere...
