Reverse Writer's-Block

As the name implies, this is the opposite of Writer's Block. This means that the writer, instead of blanking, gets an overflow of ideas- the downside is that these ideas will usually not be related to each other. For instance, an author may be trying to write a biography and, due to Reverse Writer's Block, get ideas for the biography, ideas for a story about god-knows-what, lines for a poem, characters for a script, and so on. This can be a good thing in that, due to the massive writing one does because of this, improvement can be accomplished. They can exercise grammar, word usage, and creativity. There is no cure, I'm afraid.
