Shiny and New

Well, it's happened again. I shouldn't be surprised, but yet I am. Every time I finish one manuscript and am about to dive into revisions, a shiny new idea pops into my head. Now you're probably thinking, well that's good, right? Yes and no.

I jotted my idea down and even used my digital voice recorder to record thoughts that were coming too quickly for me to write. I should be happy. I know what I'll be working on when I'm finished with revisions on my current WIP. Not quite.

This new idea won't leave me alone. It's not satisfied sitting in my writer's notebook and on my recorder. It is demanding to be written. And not just that, it's demanding to be written in present tense, something I've only done once and even then I wound up converting it to past tense. 

So I'm at a loss. What do I do? Revise? Give in to the shiny new idea?

Do you get new ideas at bad times like this? Is there really such a thing as a bad time for a shiny new idea?
