“Write the kind of story you would like to read. People will give you all sorts of advice about writing, but if you are not writing something you like, no one else will like it either.” - Meg Cabot
In other words: Don't pay attention to the market right now, to the trends that are supposed to make it big. Write a story you'd want to read, a story which excites you, a story you don't want to give up on when the writing gets though.
Set your timer. Write!
