When to Ignore Your Muse

You'd think it would be great to have a Shiny New Idea (SNI) fall into your lap, but it's not always a good thing. Don't get me wrong--I'm super excited about SNI and the hubby thinks it's a really cool premise. But...I haven't finished revising my current manuscript. The same ms I'm bringing to a writing retreat next week in order get feedback on it from editors/agents/etc. Yet the lure of this pretty, new thing is so tempting. I'm one of those writers who loves first drafts, and er, intensely dislikes tenth drafts. First drafts are fun for me, and all the drafts after it are more like work. I know some writers love the revision part of the process, and while I do love watching my book evolve and become better, I've discovered I have a slight problem with impatience.

I'm solving this problem by jotting down notes on SNI...and occasionally obsessing about it in the shower. But  for now it's back to work on revision number gazillion of my current ms. I guess there's something to be said for having motivation to finish it, so I can move on to the next thing.

Anyone else struggle with this issue, or does everyone love revisions more than I do?
