For me, there's something thrilling about organizing a drawer or closet or space and purging out what isn't necessary or useful. My husband jokes when I get into organizing mode that the rest of the family should watch out or Mom might organize them all out of the house.
Interestingly this need to organize and purge doesn't apply to the various manuscripts on my hard drive. And thank goodness for that! As I was going through my edits the other week, I found a spot where my editor felt one chapter ended too abruptly. She wanted me to add more to the scene. To my relief - and luck - I found a continuation of that scene, which I'd written about five years ago and kept on my computer - just in case. Having that scene already written made it easy to rework and plug it into the spot I needed it. So, as much as it pains me to say, there are times when it's good to keep a little clutter around.
Are you a hoarder or are you all about clearing out the clutter (a get-ridder)? What things are easy to let go of? What things are harder?
