WordPress has a simple back end with some nice features. One of the things you can do is save your posts before you publish them. This allows you to work on several articles at once or start on an idea and never finish it (more the latter than the former).
Today, after deleting a few drafts I stopped and looked at the titles that I still had left.
Just for the record, these drafts are drafts for a reason, they may not be any good; so choose wisely!
