I really don't consider my unfinished projects "UFOs". I never do the same quilt pattern twice so each quilt I start is to try something new or learn a different technique. I have given myself permission not to finish a project if I don't want to. I may get bored with it or simply just don't care for it when the top is done. I enjoy the piecing part of quilting far more than the sandwiching, quilting and binding. Quilting makes me happy and I'm not going to ruin that by stressing over unfinished projects. If I decide that I'm not happy working on something, I just put everything together to complete it and put it on a shelf. Sometimes, I will decide that the project isn't that bad and will pull it out and work on it. Or, it will sit there until I decide it needs to go away!
