I'm impressed that so many of your UFOs are at the "assembled top" stage! Mine are scattered all along the spectrum from "idea that I haven't quite figured out" to I really should finish stitching down the binding".
I'm definitely in the squirrel syndrome group. I quilt for fun, so if a different project tickles my fancy, I switch. Quilting/sewing is the only aspect of my life where I would consider taking this much freedom, so it's interesting to step out of my comfort zone and make frivolous choices.
