I really try to totally finish one before starting another, but that isn't always what happens. Usually I'm almost done piecing one and then start thinking about the next one, then it's a struggle to finish up the first one before plunging into the next one. Having a deadline to finish is sometimes good. I do have fabric and pattern bought for many projects: purses, Christmas tree skirt, OBW's, but haven't actually cut the fabric yet. So they aren't considered a UFO - are they?
