Which One to Write

Have you experienced writing from an idea then while writing, another topic comes up and you want to also write about that? Then, another idea keeps on drumming up on your head that before you realize it, you already have too much topic to write on and that you’ve created too many drafts. Yet, finishing them all is not possible because you don’t know where to begin and how to end. Or, it could be that there are many beginnings but the body seems to start another topic.

So, which one would you finish first? The original idea you wanted to write about or the thoughts that came out from that original idea? Which one would you publish first?
