Had to chuckle reading your post... Wanting to start something else before we finish the previous thing is a VERY common phenomenon. We call it Quilter's A.D.D. So many of us have succumbed to it, probably because we get so many new ideas before finishing what we are working on.
If you are bored with your first quilt and anxious to start something else, why don't you machine quilt it? You can do simple straight lines or a criss cross grid with a walking foot. That would get it done, at least, so you could move on to something more interesting.
OR... do as we all do and just set it aside for later. The Quilting Police will NOT come to your house and arrest you if you don't finish.
