I have ADD too, but I have noticed that knitters, like serious readers, have more than one thing going at a time. On another board I read someone's New Year's resolution to be a more "serial monogamy" kind of knitter, LOL. Good luck with that...
So, I don't think that ADD has anything to do with whether or not you knit one thing at a time. I know that what I exhibit as "symptoms" of ADD (trouble knowing where to start on big projects, procrastination, being easily distracted, chronic, debilitating disorganization, becoming easily overwhelmed, etc.) don't really apply to my knitting or any of my other creative endeavors. Knitters are creative people and limiting oneself to one project at a time is just masochistic. I am always keeping my eye out for the next thing to add to my ever-growing stash of yarn and book collection. If anything, knitting has taught me patience and tenacity when working on projects and learning new techniques.
So many fibers, so little time!
