When I first started writing this past February, I generally concentrated on one story at a time and worked on it until it was finished. I used the draft message sections on free email accounts to store my stories until I could paste them onto a story site. A few months later when I purchased an office suite program for my laptop I was able to store multiple stories and manage them much easier. Since then, I have gotten into the habit of writing several stories at the same time and switching to make it more interesting. I like that system now because it prevents any liklihood of a writing block.
