I'm not a good one to talk you out of starting a new project, but I might be able to help you finish the old ones. I find that I sometimes need a little pressure (from myself) to finish projects.
Sometimes it helps to tell someone else that you plan to finish this or that project by a certain time for a gift for someone. Then you feel obligated to get it done because someone is expecting to hear about the recipient receiving the gift. Really spurns me on to getting things done.
