So many ideas, so little time

So now that I've been letting my muses loose, I have no shortage of story ideas. Short stories, novels, essays. Heck, once in a while I think about a poem! 

But there in lies the problem….I have TOO many ideas. I literally have six different pieces started. 

I feel a bit like I have multiple personalities. Each piece is very different. I suppose they represent different parts of me and the topics I'm interested in. It reasons that depending on my mood any given day, a particular piece will call to me to write. If I keep following this method of writing, I'll never get anything finished!
