Sewing Attention Deficit Disorder

I know I'm not the only one. Venus de Hilo has it too. It's the lure of the new, bright beginnings, pretty colors, I want it now. She listed all of her works-in-progress, and I realized that in spite of my vow to complete each project after I started it (I promise!) when we finished my new sewing studio, I have been BAD. Currently I have the following in various stages of not-finished: blue linen capris that only need hand hemming, a Sidelines Quilt, an Apron (a gift), batik drawstring pants, and two Hawaiian shirts that need buttonholes and buttons. And I'm planning a baby quilt right now. Bad me.
Do you keep starting new things before you finish the old ones? What is it about new stuff?
