They told me that doing actual prewriting can make a paper ten times more organized and might actually earn me an A in the class. I ignored that and earned B's in high school English classes. I then go to college and it's more-or-less the same thing, but now it's my major.
Here I am now, struggling to complete my first full-length play - as in something that should be around 100 pages of text. I'm on page 16 and I've realized that I have no idea where this thing is going. So what's a boy to do? Pre-write. Completely. Essentially writing the story before actually writing the story. Not just figuring out the characters or writing out a dramatic premise, the whole thing. Scene by scene. The way I like to do this is - well - long-hand.
